| effect of prophage w on the propagation of bacteriophages t2 and t4. | studies have been undertaken to determine whether the temperate phage omega present in escherichia coli strain w is responsible for the inability of this strain to act as a host for t2 and t4. e. coli ws, cured of phage omega, was sensitive to t2 and t4. lysogenation of e. coli c and ws with phage omega resulted in loss of ability to plate t2 and t4. however, e. coli k-12 lysogens still served as hosts for the t -even phage. two of three ws lysogens studied resembled strain w at the biochemical ... | 1968 | 5701827 |

| inactivating and mutagenic effects of 1-methyl-3-nitro-1-nitrosoguanidine on intracellular bacteriophage. | 1-methyl-3-nitro-1-nitrosoguanidine (ng) was able to inactivate and mutate adsorbed but not free coliphage t2. coliphage t4 was as sensitive to ng as t2. when treatment was delayed for 5 min or longer after adsorption of t2, the phage became increasingly refractory to ng inactivation. | 1968 | 5725321 |
| t4 bacteriophage mutants suppressible by a missense suppressor which inserts glycine in place of arginine for the codon aga. | phage mutants of t4 have been isolated which can multiply only on escherichia coli strains which contain a missense suppressor which is known to cause the substitution of glycine for arginine in response to the aga codon. mutations producing the suppressible phenotype were mapped and shown to occur in six different phage cistrons. two of the cistrons were concerned with deoxyribonucleic acid synthesis, two were concerned with phage structural components, and two were concerned with functions req ... | 1968 | 5725322 |

| acridine binding by escherichia coli: ph dependency and strain differences. | acridine dye binding by cells of escherichia coli has been characterized in terms of a number of parameters. there is a temperature-dependent, readily reversible binding of acriflavine which occurs to a greater extent with acridine-sensitive mutants of e. coli k-12 than with wild-type e. coli b or k-12. there is an essentially irreversible internal binding of acriflavine which occurs when the cellular permeability barriers are destroyed or altered by heat-treatment, elevated ph, treatment with t ... | 1968 | 4867737 |

| phospholipid synthesis in escherichia coli infected with t4 bacteriophages. | after infection of escherichia coli with t4 phage, phospholipid synthesis continued but at a reduced rate. the same phospholipid components were synthesized as in uninfected cells; however, the relative rates of (32)p(i) incorporation into phosphatidylglycerol (pg) and phosphatidylethanolamine (pe) were altered. this alteration was most pronounced during the first 10 min after infection. under these conditions, the isotope incorporated into pg equaled or exceeded that found in pg from uninfected ... | 1968 | 4880428 |

| host-controlled restriction of t-even bacteriophages: relation of endonuclease i and t-even-induced nucleases to restriction. | restriction of nonglucosylated t2 phage (t(*)2) as a function of bacterial growth state was the same for endonuclease i-containing and endonuclease i-deficient strains of escherichia coli b. furthermore, e. coli strains with various levels of restriction for t2 had comparable endonuclease i activities. it was also found that a t4 mutant temperature-sensitive for gene 46 and 47 functions was fully restricted at 42 c. it therefore appears that neither endonuclease i nor the phage-induced nucleases ... | 1968 | 4911845 |
| bacteriophage-induced inhibition of host functions. i. degradation of escherichia coli deoxyribonucleic acid after t4 infection. | the kinetics of degradation of bacterial deoxyribonucleic acid (dna) after infection of escherichia coli with t4d, ultraviolet-irradiated t4d, and two amber mutants, n122 and n94, was studied by zone sedimentation through linear glycerol gradients. within 5 min after infection with any of the bacteriophages, breakdown of host genome was evident. the first product was a high-molecular-weight material (50s to 70s) and further degradation appeared to occur in discrete steps. rapid and extensive bre ... | 1968 | 4911847 |
| reversible repression of early enzyme synthesis in bacteriophage t4-infected escherichia coli. | a mutant of escherichia coli b, defective in its accumulation of k(+), was found to synthesize protein at a rate proportional to the level of this cation in the growth medium. when bacteriophage t4-infected cells were incubated in growth medium containing 1 mm k(+), phage deoxyribonucleic acid (dna) was synthesized at a rate 25% that of normal, and phage protein was synthesized at a rate of 50% of normal. deoxycytidine pyrophosphatase, a phage-directed early enzyme, shut off at a level of 55% th ... | 1968 | 4911851 |
| control of lysis of t4-infected escherichia coli. | the lysis of escherichia coli b/5 infected with t4dr48 could be delayed by addition of 9-aminoacridine (9aa). infected cells showed an early period of maximal response followed by a decline in sensitivity. the ultimate rate of lysis was also affected by the dye. deoxyribonucleic acid (dna), protein, and lysozyme synthesis began at the normal time in complexes inhibited by 9aa addition. the rates of synthesis of these macromolecules were lower in the presence of the dye, with dna and lysozyme syn ... | 1968 | 4911852 |

| the luria-latarjet effect studied by t4-lysozyme production. | the replication of bacteriophage t4 in escherichia coli is sensitive to ultraviolet light (uv). the classical plaque assay shows a considerable increase in uv resistance starting at about 5 minutes after the bacteria are infected. production of phage lysozyme starts about 10 minutes after infection and is sensitive to irradiation. its uv resistance increases at about 4 minutes. the appearance of resistance, measured by both the plaque assay and lysozyme production, is inhibited by p-fluorophenyl ... | 1968 | 18614109 |
| cellular heterogeneity in the production of an anti-hapten antibody. | single lymph node cells from rats immunized with a conjugate of 3-iodo-4-hydroxy-5-nitrophenyl acetic acid chloride (nip) and chicken globulin were tested against either nip or nnp conjugated with bacteriophage. nnp is related to nip but has a nitro group instead of iodine. the conjugated phages were still infective but easily inactivated by anti-hapten sera at a serum concentration of 10(-7). phages carrying a related hapten were less sensitive to antibody than phages conjugated with the immuno ... | 1967 | 4165500 |

| control of bacteriophage-induced enzyme synthesis in cells infected with a temperature-sensitive mutant. | the timing of "early" and "late" protein synthesis in escherichia coli infected with t-even bacteriophage was studied with a temperature-sensitive phage mutant, t4 tsl13. this strain was completely unable to direct the synthesis of phage deoxyribonucleic acid (dna) at 44 c because it makes a deoxycytidylate hydroxymethylase which cannot act at that temperature. however, the mutant did multiply normally at 30 c. no detectable formation of the late protein, lysozyme, occurred at 44 c, in agreement ... | 1967 | 4918234 |

| lysis inhibition in escherichia coli infected with bacteriophage t4. | a technique of continuous filtration of t4-infected escherichia coli has been devised to study the phenomenon of lysis inhibition. studies using this technique revealed that the length of the lysis delay caused by superinfection can attain only certain discrete values, which for low average multiplicity of superinfection is thought to be a reflection of the actual number of superinfecting particles per cell. the time interval between primary and superinfection had little effect on the length of ... | 1967 | 4912240 |
| growth of a dihydrofolate reductaseless mutant of bacteriophage t4. | a mutant of bacteriophage t4 was isolated which was unable to induce virus-specific dihydrofolate reductase in infected cells. the mutant was able to form several other early enzymes of pyrimidine metabolism. growth of the mutant in a wild-type host, escherichia coli b, was compared with that of the parent strain, t4bo(1), and t4td8, a mutant which lacks the ability to induce thymidylate synthetase. growth studies were carried out in minimal medium, which gave higher growth rates and phage yield ... | 1967 | 4912241 |
