| regulation of the expression of the n gene of bacteriophage lambda. | a quantitative assay for the n protein of bacteriophage lambda has been used to study the in vivo regulation of n gene expression. the assay makes use of the observation that in a cell-free protein-synthesizing system from escherichia coli programmed with lambdan(-) dna the lambda endolysin is made only if n protein is added to the reaction. the rate of synthesis of n protein in vivo is negatively controlled by the products of the ci and tof genes of the phage. furthermore, n protein activity is ... | 1973 | 4568728 |

| isolation of the bacteriophage lambda receptor from escherichia coli. | a factor which inactivates the phage lambda can be extracted from escherichia coli. this factor is a protein and is located in the outer membrane of the bacterial envelope. it is found in extracts of strains which are sensitive to phage lambda, but not in extracts of strains specifically resistant to this phage. we conclude that this factor is the lambda receptor, responsible for the specific adsorption of the phage lambda to e. coli cells. a partial purification of the lambda receptor is descri ... | 1973 | 4201774 |
| purification and properties of the gamma-protein specified by bacteriophage lambda: an inhibitor of the host recbc recombination enzyme. | previous experiments have indicated that the gam gene of bacteriophage lambda is responsible for an inhibition of the recbc dnase-an enzyme that is essential for the major host pathway of genetic recombination. we report here experiments that define the inhibitor as the protein product of the gam gene ("gamma-protein") and that characterize the inhibition reaction with highly purified preparations of gamma-protein and recbc dnase. genetic characterization was performed with partially purified fr ... | 1973 | 4275917 |

| lambda phage dna: joining of a chemically synthesized cohesive end. | the chemically synthesized dodecamer d(pa-g-g-t-c-g-c-c-g-c-c-c) was annealed, and was covalently joined to lambda phage dna with bacterio-phage t(4) ligase. the 5'-end of the dodecamer was joined to a deoxyguanosine residue. repair with dna polymerase i established that the position of joining was the left-hand end of lambda dna. this is the first time that a chemically synthesized oligonucleotide has been covalently joined to a naturally occurring dna molecule. | 1973 | 4566655 |
| in vitro assembly of bacteriophage lambda heads. | the assembly of plaque-forming particles in cell-free extracts of induced lambda lysogens was observed two ways. (i) dna isolated from a lambda-related phage, 434 for example, is added to an extract of an induced lambda lysogen, and plaque-formers with the genotype of the added dna are detected. (ii) one extract from an induced lambda lysogen that carries an amber mutation in one of the head genes (a, b, c, d, or e) is mixed with one carrying an amber mutation in a different head gene; an increa ... | 1973 | 4509659 |
| multiple repressor binding at the operators in bacteriophage lambda. | short dna duplexes are protected when lambda dna is digested with nuclease in the presence of lambda repressor. as the ratio of repressor to operator is increased, six successively larger fragments are recovered, ranging in size from 35 to 100 base pairs, each of which binds repressor. study of these fragments indicates that, at each of the two lambda operators (o(l) and o(r)), repressor first binds to a unique site (not necessarily terminal), and that five additional sites are then filled in li ... | 1973 | 4514322 |
| regulation by n gene protein of phage lambda of anthranilate synthetase synthesis in vitro. | the n protein of bacteriophage lambda is a positive regulator of early lambda gene expression. in a lambdatrp transducing phage, lambdatrp46nam, the synthesis of trp enzymes in vivo is also dependent on the presence of active n protein. the dna of this phage has been used in a protein-synthesizing system in vitro to develop a biochemical assay for the activity of the n protein. from the following observations it appears that it is the n protein itself that stimulates trp enzyme synthesis in vitr ... | 1973 | 4515605 |
| the 3'-terminal nucleotide sequences of bacteriophage lambda dna. | analyses of radioactive oligonucleotides in endonuclease digests of 3'-terminally labeled lambda dna revealed the 3' terminal sequence -gttacg for the l strand and -acccgcg for the r strand. these sequences, together with those previously known for the 5' cohesive ends, provide a total of 25 known base-pairs in the vicinity of the termini. when the cohesive ends are paired, the sequence between the nicks can be bisected by a 2-fold rotational axis of symmetry. five of the first eight base-pairs, ... | 1973 | 4515613 |

| genetic mapping of the inversion loop in bacteriophage mu dna. | an inversion loop seen in heteroduplex mapping of the dna of mature mu phage induced from a lysogen is observed also in defective lambda phage carrying one end of mu. 14% of the dna of mu, including this region, designated the g loop, is shown to be to the right of all known genes in the prophage map. the inhomogeneous ends of mu are observed as a separate phenomenon and appear in all mutants investigated. the reca and recbc functions of the host are not needed for the inversion responsible for ... | 1973 | 4516210 |
| alignment of two dna helices: a model for recognition of dna base sequences by the termini-generating enzymes of phage lambda, 186, and p2. | based on the 3'- and 5'-terminal sequences of dna of phage lambda, p2, and 186, a model is proposed for recognition of dna sequences by enzymes responsible for generation of cohesive ends. two copies of the cohered ends, either on separate molecules or on a concatemer, are aligned with their helical axes parallel but running in opposite directions. the nicking system is dimeric, with each of the two monomers carrying identical sequence-recognition sites. two pairs of nicks are introduced into th ... | 1973 | 4517677 |

| ultraviolet-sensitive mutator strain of escherichia coli k-12. | an ultraviolet (uv)-sensitive mutator gene, mutu, was identified in escherichia coli k-12. the mutation mutu4 is very close to uvrd, between mete and ilv, on the e. coli chromosome. it was recessive as a mutator and as a uv-sensitive mutation. the frequency of reversion of trpa46 on an f episome was increased by mutu4 on the chromosome. the mutator gene did not increase mutation frequencies in virulent phages or in lytically grown phage lambda. the mutu4 mutation predominantly induced transition ... | 1973 | 4345920 |
| in vitro repression of the transcription of gas operon by purified gal repressor. | we have studied the in vitro repression of gal mrna synthesis by the gal repressor from escherichia coli. by use of a four-step purification procedure involving chromatography on phosphocellulose, deae-cellulose, and an affinity resin, the gal repressor has been purified about 1600-fold from a crude cell extract. the purification was aided by use of a cell extract made after prophage induction of cells lysogenic for bacteriophage lambda that carries the gal repressor gene (galr). the highly puri ... | 1973 | 4346883 |
| genetic and biochemical investigation of the escherichia coli mutant hfl-1 which is lysogenized at high frequency by bacteriophage lambda. | the escherichia coli mutant hfl-1 is lysogenized at very high frequency by bacteriophage lambda. the normal requirement for the lambdaciii gene product in the establishment of repression is not observed in hfl-1 strains. these phenotypic characteristics are specified by a single locus at 82.5 min on the e. coli map in extremely close proximity to the pura gene, cotransduction frequencies ranging from 97 to 100% depending on the particular pura marker used. the lactose operon is shown to function ... | 1973 | 4352176 |
| nucleotide sequence analysis with polynucleotide kinase and nucleotide "mapping" methods. 5'-terminal sequences of deoxyribonucleic acid from bacteriophages lambda and 424. | the polynucleotide kinase reaction was used in analyses of complex mixtures of oligodeoxynucleotides which were fractionated by various two-dimensional nucleotide ;mapping' procedures. parallel ionophoretic analyses on deae-cellulose paper, ph2, and ae-cellulose paper, ph3.5, of venom phosphodiesterase partial digests of 5'-terminally labelled oligonucleotides enabled the sequence of the nucleotides to be deduced uniquely. a ;diagonal ionophoresis' method has been used with mixtures of nucleotid ... | 1973 | 4352720 |
| isolation of a mutant of escherichia coli defective in cytosine-specific deoxyribonucleic acid methylase activity and in partial protection of bacteriophage lambda against restriction by cells containing the n-3 drug-resistance factor. | a mutant (designated mec(-)) of escherichia coli f(+) 100 endo i(-)su(+) r(k) (-)m(k) (+) has been isolated which is defective in cytosine-specific deoxyribonucleic acid (dna) methylase activity. the dna of this mutant, as well as the dna of phages lambda and fd propagated in it, is virtually devoid of 5-methyl-cytosine (mec); in contrast, the mutation has no significant effect on the level of n(6)-methyladenine in dna. phage lambda grown on the mec(-) mutant is more strongly restricted by n-3-c ... | 1973 | 4353870 |

| the roles of the lambda c3 gene and the escherichia coli catabolite gene activation system in the establishment of lysogeny by bacteriophage lambda. | maximum lysogenization of e. coli by bacteriophage lambda requires both the lambdaciii gene function and the host catabolite gene activation system mediated by adenosine 3':5'-cyclic monophosphate. whereas considerable lysogenization occurs in the presence of either system alone, lysogenization is absolutely prevented in the absence of both systems. neither system is, however, required for efficient lysogenization when the host bears an hfl(-) mutation. it is argued that the normal function of t ... | 1974 | 4362632 |
| threonine locus of escherichia coli k-12: genetic structure and evidence for an operon. | three genes, thra, thrb, and thrc, were previously defined and localized in the threonine locus of escherichia coli k-12. thra, thrb, and thrc specify the enzymes aspartokinase i-homoserine dehydrogenase i, homoserine kinase, and threonine synthetase, respectively. a complementation analysis of the threonine cluster using derivatives of a lambda phage carrying the threonine genes (lambdadthr(c)) demonstrates that: (i) thrb and thrc each consist of a single cistron; and (ii) thra is composed of t ... | 1974 | 4364333 |

| int-constitutive mutants of bacteriophage lambda. | the constitutive production of small amounts of trpb enzyme in an escherichia coli strain carrying lambdaci857 prophage within the trpc gene has been examined in derivatives of this strain from which portions of the prophage have been deleted. enzyme production requires a site (p(i)) within the prophage close to the left prophage end. selection for mutants of this lysogen that grow on low concentrations of indole yielded two types of mutations within the prophage: (a) v2-type, in which all phage ... | 1974 | 4521054 |
| protein fusion: a novel reaction in bacteriophage lambda head assembly. | parts of two phage-coded head proteins, pe and pc, become fused during bacteriophage lambda head assembly. pe is the main structural component of lambda heads and pc is a minor head protein that is not found as such in mature heads. the bond joining the two proteins appears to be covalent and is not a disulfide bond. only a specific subset of the sequences of each protein is found in the fusion products, and these sequences are found in the products in equimolar amounts. two nearly identical fus ... | 1974 | 4524648 |
| on the molecular basis of high negative interference. | two models designed to account for high negative interference phenomena have been examined. one proposal suggests that many recombination events are the result of insertion of a small single-stranded segment of dna into a recipient molecule. an alternative explanation for the clustering of genetic exchanges is reduction to homozygosity of genetically heterozygous sites appearing within heteroduplex overlap regions. these proposals have been examined in phage lambda by analyzing the structure of ... | 1974 | 4524657 |
| synthesis of bacteriophage lambda dna in vitro: requirement for o and p gene products. | we have developed a cell-free system to study bacteriophage lambda dna replication. maximal dna synthesis in vitro requires the four deoxynucleoside triphosphates, atp, and exogenous lambda dna. dna synthesis requires the products of the phage o and p genes but is not inhibited by lambda repressor. the kinetics of synthesis is linear for 10-15 min; however, the product of synthesis amounts to only 0.5-1% of the added template dna. as judged by isopycnic analysis, extensive regions of the templat ... | 1974 | 4525790 |
| in vitro genetic recombination of bacteriophage lambda. | dna of bacteriophage lambda recombines in a cell-free extract prepared from an induced escherichia coli lysogen of bacteriophage lambda. the assay for recombination in vitro takes advantage of the ability of such an extract to package lambda dna and to assemble complete phage particles. for example, when lambda dna that has been extracted from phage with the immunity of 434 is added to an extract, infectious lambda imm 434 particles are produced. the precursor dna molecule in this packaging reac ... | 1974 | 4526306 |
| bacteriophage lambda having ecori endonuclease sites only in the nonessential region of the genome. | a derivative of lambda b221 that has lost by mutation all ecori restriction sites has been isolated by alternative growth on restrictive and nonrestrictive strains. it has an efficiency of plating equal to 1 on the restrictive strain. genetic cross of this bacteriophage with lambda plac5 imm21 gave rise to recombinants of intermediate restricting ratios. the analysis of the ecori endonuclease-cleaved dna by polyacrylamide gel electrophoresis, compared with the genetic results, has permitted iden ... | 1974 | 4530273 |

| rec-mediated recombinational hot spot activity in bacteriophage lambda. i. hot spot activity associated with spi-deletions and bio substitutions. | in order to survey the distribution along the bacteriophage lambda chromosome of rec-mediated recombination events, crosses are performed using conditions which block essentially all dna synthesis. one parent is density-labeled and carries a genetic marker in the left terminal lambda gene (a), while the other parent is unlabeled and carries a genetic marker in the right terminal lambda gene (r). both parents are deleted for the lambda recombination genes int and red, together with other recombin ... | 1974 | 4415484 |
| rec-mediated recombinational hot spot activity in bacteriophage lambda. ii. a mutation which causes hot spot activity. | crosses have been performed which identify phage mutants (chi) which cause recombinational hot spot activity in lambda. the hot spot activity is found in crosses of red(-) gam(-) chi(-) strains in rec(+) hosts; in the crosses reported here, both the chi(-) mutations and the hot spot are located near the right end of the chromosome. the hot spot occurs in standard crosses as well as under conditions which block dna synthesis, and is dependent on a functional host recb gene.-the chi mutation is sh ... | 1974 | 4415485 |

| the distribution of crossovers along unreplicated lambda bacteriophage chromosomes. | the distribution of crossovers along unreplicated chromosomes of bacteriophage lambda has been examined by determining the density distributions and genotypes of particles in the progenies of crosses of density-labeled by ordinary parents in the presence of genetic blocks to replication. the red and rec systems combined produce crossovers primarily near the ends (especially the right end) of the chromosome. removal of the generalized lambda recombination functions by red and gam mutations result ... | 1974 | 4416166 |
| structure of isometric viruses containing nonidentical polypeptide chains. | the theory of caspar and klug (1962) for the structure of isometric viruses has been generalized to the case in which the identical repeating unit is composed of n nonidentical polypeptide chains. this modified theory accounts for the structure of picornaviruses, the lambda phage head, cowpea mosaic virus, and phix174, while at the same time conserving the principle of having identical subunits in identical environments. furthermore, the modified theory suggests amending the triangulation number ... | 1974 | 4418754 |

| mechanism of inhibition of bacillus subtilis dna polymerase 3 by the arylhydrazinopyrimidine antimicrobial agents. | arylhydrazinopyrimidines inhibit dna synthesis in bacillus subtilis by promoting formation of a specific, long-lived ternary complex with dna polymerase iii and the template-primer dna. dna polymerase iii contains an associated, single-strand-selective exonuclease which generates 5'-mononucleotides. drug inhibition of the nuclease similarly proceeds through formation of the ternary complex. the ternary complex was isolated by agarose chromatography. like inhibition of the nuclease, optimum forma ... | 1974 | 4213240 |

| size distribution and molecular polarity of newly replicated dna in escherichia coli. | newly synthesized dna, in e. coli lysogenic for the phage lambda, was labeled by short pulses of [(3)h]-thymidine, isolated, and separated on the basis of size by alkaline sucrose density gradient centrifugation. the molecular polarity of this dna was determined by hybridization with each of the separated strands of lambda dna. the results show that, in the 3' to 5' direction, replication proceeds by synthesis of short chains that are subsequently joined to long dna. this is true for both a pola ... | 1974 | 4592688 |
| interaction of bacterial and lambda phage recombination systems in the x-ray sensitivity of escherichia coli k-12. | e. coli cells lysogenic for the thermoinducible prophage lambdaci857 can be transiently induced by a brief heat treatment. although this treatment does not kill the cells, some lambda products normally formed during vegetative phage development are made that can alter the response of host cells to x-irradiation by causing an increase in radioresistance. this increased resistance is particularly striking in the recombination-deficient recb-strain, which is normally much more radiosensitive than i ... | 1974 | 4592694 |
