| 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 |

| initiation of infection by deoxyribonucleic acid from . . . bacteriophage lambda. | kinetic studies conducted on the early stages of infection of escherichia coli k-12 by deoxyribonucleic acid (dna) isolated from bacteriophage lambda indicate a rapid adsorption of the phage dna to receptor sites at the bacterial surface prior to deoxyribonuclease-insensitive incorporation. a direct relationship found between the number of dna molecules adsorbed per bacterium and the multiplicity of helper phage infection indicates a requirement for helper function during the attachment process. ... | 1967 | 4960182 |

| protein components of bacteriophages lambda and lambda virulent. | parallel studies have been made of the protein coats of the temperate bacteriophage lambda and of a deletion mutant, lambda virulent. a new method for preparing ghosts of both phages by the action of cu(++) is described. protein ghosts of both phages can be dissolved in citrate at ph values below 3, more rapidly in the presence of 8 m urea. both phages yielded three apparently identical protein components which can be separated by thin-layer gel filtration and thin-layer gel electrophoresis. the ... | 1967 | 5621486 |

| early functional mutants of . . . coliphage lambda. | the early functional mutants of lambda, belonging to cistrons n, o, and p, are known to be blocked prior to vegetative multiplication of the lambda genome. superinfection of heteroimmune defective lysogens by these mutants failed to elicit the function required for replication of the superinfecting phage. the mutants among themselves also showed poor cooperation on a nonpermissive host. studies on the effects of different multiplicities of infection for bacterial lysis showed identical responses ... | 1967 | 6020563 |

| mutations in bacteriophage lambda affecting host cell lysis. | nine temperature-sensitive and defective mutants of phage lambda deficient in lysis of the host cell have been analyzed in respect to location of the site of mutation and phenotypic properties. seven of the isolates are mutant in cistron r and produce either a thermolabile endolysin or no detectable enzyme. the remaining two mutants, one temperature-sensitive and one defective, produce high levels of apparently normal enzyme. these mutants denote the involvement of at least one phage cistron oth ... | 1967 | 18614056 |
| fractionation of the complementary strands of coliphage lambda dna based on the asymmetric distribution of the poly i,g-binding sites. | poly i,g interacts preferentially with one of the two complementary dna strands of lambda and lambda-related phages 21, 434, and phi80, thus permitting preparative separation of the "dense" fraction, consisting of a complex between the intact strands c and poly i,g, from the less dense ("light") fraction containing the intact strands w, which bind 3-4 times less poly i,g. the isolated and self-annealed fractions are over 99% pure as far as their hybridization properties with complementary rna ar ... | 1967 | 18614063 |
| effects of uncouplers of oxidative phosphorylation on the infection of escherichia coli k12 by phage-lambda dna. | some effects of two uncouplers of oxidative phosphorylation on infection of escherichia coli k12 by bacteriophage lambda deoxyribonucleic acid (dna) are described. dinitrophenol did not interfere with the initial interaction of the cells with free dna, and neither dinitrophenol nor carbonyl cyanide m-chlorophenylhydrazone affected the linear portion of the infection reaction. however, the process by which lambda-dna bound to the bacterial cell became insensitive to deoxyribonuclease was strongly ... | 1967 | 18614068 |
| an investigation of bacteriophage lambda, its protein ghosts and subunits. | the sedimentation coefficients and molecular weights of bacteriophage lambda and its ghost were determined as so(20,w) = 416 x 10(-13) second and m = 57 x 10(6) for the virus, and so(20,w) = 141 x 10(-13) second and m = 21 x 10(6) for the ghost. the protein portion of the virus consists of at least two distinct types of subunits, with molecular weights of 55,000 and 110,000, which differ markedly in their amino acid content. | 1967 | 18614077 |

| host survival following infection with or induction of bacteriophage lambda mutants. | the lethal effects of lambda infection and lambda induction were studied using conditional lethal mutants of phage lambda in the su- host w3350. phage with mutations in q and r, which are blocked after dna replication, kill promptly and efficiently on induction or infection. infection with mutants defective in o and p, which do not replicate, kills less efficiently, although these mutants do kill effectively at high multiplicity of infection. heat induction of lysogens carrying dna defective mut ... | 1968 | 18614112 |
| suppressor-sensitive mutants of coliphage phi80. | about fifty suppressor sensitive (sus) mutants of phage phi80 were isolated after hydroxylamine treatment, and these were classified into fourteen cistrons. in vitro and in vivo complementation experiments revealed that at least five cistrons were concerned with head formation and that at least six cistrons were concerned with tail formation in phi80. some presumed "early" mutants were also found. defective lysogens were isolated from a phi80-lysogenic nonpermissive strain using the colicin plat ... | 1968 | 18614128 |
| production of single-strand breaks in covalent circular lambda phage dna in superinfected lysogens by monoalkylating agents and the joining of broken dna strands. | fast sedimenting, double-stranded, covalent circular lambda phage dna in superinfected lysogens of escherichia coli is converted to notched circular dna, sedimenting slowly in alkaline sucrose gradients, by methylmethane sulfonate (mms) treatment during incubation at 37 degrees . during further incubation after removal of the mms, the slow sedimenting dna reverts to the fast sedimenting structure. covalent circular dna, phenol extracted from superinfected lysogens and exposed to mms, ethylmethan ... | 1968 | 18614129 |

| disruption of t-even bacteriophages by dimethyl sulfoxide. | dimethyl sulfoxide (dmso) disrupted t-even bacteriophages as well as lambda bacteriophage. the component substructures of t2l, t4b01, or t6, in particular heads, were readily isolated after treatment with 67% dmso (v/v). in contrast, concentrations of dmso above 50% not only separated heads from tails of bacteriophage lambda but led to degradation of the lambda heads. examination of the isolated free heads of t-even bacteriophage indicated that a distinct neck substructure was attached to one ap ... | 1968 | 5697471 |

| effect of mutation to streptomycin resistance on amber suppressor genes. | three classes of nonidentical streptomycin-resistant mutations were distinguished in escherichia coli by their effect on the efficiency of suppression by an amber suppressor gene, sup e. the first class of mutation caused a strong restriction in efficiency of suppression of an amber codon in various cistrons of phage lambda and in an alkaline phosphatase structural gene of e. coli. the second class caused weak restriction, and the third class caused no restriction. the restrictive effect of the ... | 1968 | 4874314 |
