| leakiness of pleiotropic maltose-negative, bacteriophage lambda-resistant mutants of escherichi coli k-12. | cultures of escherichia coli k-12 mala(-)lambda(r)gal(-) can be transduced to gal(+) by bacteriophage lambdadg because of leakiness of the lambda(r) phenotype. the efficiency of such transduction is about 10(-5) that of transduction of mal(+)lambda(s) bacteria. leaky cells (lambda(s)phenocopies) adsorb only very few phage particles, and many transductants, therefore, are defective heterogenotes or show integration of the gal(+) gene, which is unaccompanied by lysogenization. | 1969 | 4905538 |

| behavior of coliphage lambda in hybrids between escherichia coli and salmonella. | salmonella typhosa hybrids able to adsorb lambda were obtained by mating s. typhosa recipients with escherichia coli k-12 donors. after adsorption of wild-type lambda to these s. typhosa hybrids, no plaques or infective centers could be detected. e. coli k-12 gal(+) genes carried by the defective phage lambdadg were transduced to s. typhosa hybrids with hft lysates derived from e. coli heterogenotes. the lysogenic state which resulted in the s. typhosa hybrids after gal(+) transduction differed ... | 1970 | 4908675 |

| bacteriophage lambda; abortive infection of bacteria lysogenic for phage p2. | the efficiency of plating of wild-type lambda on a host lysogenic for p2 is less than 10(-6), and only a small number of infected cells produce progeny phage. lambda can adsorb and inject its dna normally in such cells; the dna can circularize and is not nicked or degraded, but replication is severely impaired. mutants of p2, which as prophages no longer interfere with lambda, have been isolated and found to be recessive to wild type, implying that p2 prophage codes for a diffusible product invo ... | 1970 | 4913204 |

| behavior of lambda bacteriophage in a recombination deficienct strain of escherichia coli. | the behavior of lambda phage in the rec(-) strain jc-1569 is compared with that in the rec(+) strain jc-1557. no difference deemed significant was noted in the adsorption rate, latent period, burst size, frequency of lysogenization, and frequency of vegetative phage recombination. the location of the prophage and its mode of insertion in the rec(-) lysogen of wild-type lambda (lambda(+)) were inferred to be normal from the results of conjugational crosses. spontaneous and ultraviolet (uv) irradi ... | 1967 | 4918235 |

| temperature sensitivity of maltose utilization and lambda resistance in escherichia coli b. | escherichia coli b strains that have acquired the malb region from e. coli k-12 are able to utilize maltose and to adsorb phage lambda when grown at 30 c, but when grown at 40 c they do not absorb phage lambda and are devoid of amylomaltase activity. these mal(ts) lam(ts) cells can be mutated or transduced to become able to grow on maltose at 40 c, but they still have no detectable amylomaltase activity nor functional lambda receptors at that temperature. this mal(40) phenotype is governed by a ... | 1971 | 4934064 |

| role of exonuclease and beta protein of phage lambda in genetic recombination. v. recombination of lambda dna in vitro. | the sequential action of lambda exonuclease and polynucleotide ligase upon redundant joint molecules is sufficient to produce intact polynucleotide chains and heat-stable, biologically active molecules of lambda dna, whereas the action of ligase alone is insufficient. these results (a) confirm the previously described mechanism of single-strand assimilation, including a subsidiary mechanism by which the further action of lambda exonuclease is arrested when a redundant strand is completely assimi ... | 1971 | 4934524 |
| ultraviolet- and x-ray-induced responses of a deoxyribonucleic acid polymerase-deficient mutant of escherichia coli. | escherichia coli k-12, polal(-) is a mutant strain whose extracts are deficient in kornberg deoxyribonucleic acid (dna) polymerase activity. we have compared the mutant and parental strains on the basis of a number of responses to ultraviolet (uv) and x-irradiation. for both types of radiation, the mutant is more sensitive by approximately the same factor as measured by reduction in colony formation, depression of dna synthesis, and enhancement of dna degradation. the rate of repair of x-ray-ind ... | 1971 | 4935330 |

| purification and properties of 3-deoxy-d-arabinoheptulosonic acid-7-phosphate synthetase (phe) from a lambda arog+ transductant of escherichia coli. | by incorporating arog, the structural gene for 3-deoxy-d-arabinoheptulosonic acid-7-phosphate (dahp) synthetase (phe), into the genome of a heat-inducible susr60 mutant of phage lambda, it has been possible to increase the intracellular levels of dahp synthetase (phe) in a lysogenized strain of escherichia coli some 15-fold over levels found in the wild-type strain. by using this strain, the enzyme has been purified approximately 2,000-fold compared with wild type, and various kinetic parameters ... | 1971 | 4937786 |
| inactivation of escherichia coli, f' episomes at transfer, and bacteriophage lambda by psoralen plus 360-nm light: significance of deoxyribonucleic acid cross-links. | we have investigated some biological consequences of light-induced psoralen-deoxyribonucleic acid (dna) adducts and find that for several escherichia coli functions (killing of strain ab2480 reca13 uvra6, inactivation of phage lambda plaque-forming ability in wild type and uvra6 hosts, loss of ability to transmit intact flac(+) episomes), a light exposure sufficient for production of a single cross-link per dna molecule correlates well with the biological consequence. although one cross-link per ... | 1971 | 4937788 |

| sensitivity of intracellular bacteriophage lambda to colicin ca42-e2. | treatment of escherichia coli k-12 infected by lambda cits857 with colicin ca42-e2 resulted in partial inhibition of the infectious process. uninfected bacteria were killed by colicin with a probability of about five times that with which similarly treated lambda-infected bacteria lose plaque-forming ability. the lambda deoxyribonucleic acid (dna), when present in a bacterial cell either as the replicating dna of infectious phage or as the nonreplicating dna of superinfecting phage, was degraded ... | 1971 | 4943074 |

| bacterial mutants in which the gene n function of bacteriophage lambda is blocked have an altered rna polymerase. | bacterial mutants have been isolated, called gron, that block phage development by interference with the action of the product of the phage n gene. lambdatrp phages, which depend on the n product for the synthesis of tryptophan enzymes, do not make these enzymes in gron bacteria. two type of phage mutants have been isolated that can overcome the gron block. one type makes an altered n product, the other contains an n-bypass mutation. the gron mutation is closely linked to the rifamycin-resistanc ... | 1971 | 4943550 |
| establishment and maintenance of repression by bacteriophage lambda: the role of the ci, cii, and c3 proteins. | to define the events necessary for the establishment and maintenance of repression in a lambda-infected cell, we have studied the requirements for efficient synthesis of the ci protein ("lambda-repressor"). three classes of lambda mutants defective in the establishment of repression are also defective in the appearance of ci protein activity at the normal time. two of these mutational classes (cii(-) and ciii(-)) probably result from inactivation of lambda-specified proteins, but the third class ... | 1971 | 4943791 |
