| 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 |

| two modes of in vivo transcription for genes 43 and 45 of phage t4. | sensitivities of the expression of early genes of phage t4 to uv light were determined at various stages of intracellular development of t4 wild type, a dna-negative mutant (t4 do), and t4 tsg1, (a mutant that exhibits delayed expression of some t4 early genes). whereas the sensitivities of some genes in the t4 wild type and t4 do remain constant, genes 43 and 45 exhibit greatly reduced sensitivities several minutes after the onset of phage development. since uv sensitivities are a measure of th ... | 1974 | 4847327 |
| point mutants in the d2a region of bacteriophage t4 fail to induce t4 endonuclease iv. | we have studied the properties of presumptive point mutants in the d2a region of bacteriophage t4. dominance tests showed that the d2a mutation was recessive to the wild-type allele. the mutations were shown to map in the d2a region by complementation against rii deletions. the d2a mutations were also located between gene 52 and riib by two- and three-factor crosses. the mutants are located at at least two distinct loci in the d2a region. the point mutants grow normally on all hosts tested and n ... | 1974 | 4847325 |

| structural aberrations in t-even bacteriophage. v. effects of canavanine on the maturation and utilization of specific gene products. | previous results have shown that when a t-even bacteriophage-infected cell was exposed to l-canavanine followed by an exposure to l-arginine, a monster phage particle, termed a lollipop, was formed. l-canavanine was necessary for the induction event but l-arginine was required for the maturation of the particle. we now describe the effects of canavanine on the maturation of certain t4 proteins and their role in the induction of lollipops. the cleavage reactions of the head proteins p22, p23, p24 ... | 1974 | 4833614 |
| structural aberrations in t-even bacteriophage. iv. parameters of induction and formation of lollipops. | previous results from our laboratory have shown that when a t-even bacteriophage-infected bacterial cell was exposed to l-canavanine followed by an l-arginine chase, a monster phage particle, termed a lollipop, was formed. we now describe certain parameters concerning (i) the induction and (ii) the formation of t4 lollipops. the induction step involves a t4 late function, and can require only a 3-min exposure to l-canavanine. short pulses of l-canavanine result in the formation of shorter lollip ... | 1974 | 4833613 |

| replicative hybrid of t4 bacteriophage dna. | hybrid density replicative t4 dna was isolated from cscl, sheared, and reanalyzed in cscl. the results rule out a branched model for t4 dna replication and confirm that t4 dna replicates to a conventional, semiconservative, colinear hybrid. | 1973 | 4747988 |
| multiple initiation of bacteriophage t4 dna replication: delaying effect of bromodeoxyuridine. | effects of bromodeoxyuridine (budr) substitutions in phage t4 dna on the initial stages of dna replication were investigated. electron microscope studies of partially replicated, light (thymidine-containing) t4 dna revealed the presence of multiple loops and forks. these dna preparations had no budr in either parental or newly synthesized dna, and the observations thus show that multiple initiation of dna replication is a normal event in t4 development and is not caused by the presence of budr. ... | 1973 | 4747986 |

| bacteriophage t4 head maturation: release of progeny dna from the host cell membrane. | we have presented a new approach to studying bacteriophage t4 head maturation. using a modified m-band technique, we have shown that progeny deoxyribonucleic acid (dna) was synthesized on the host cell membrane throughout infection. this dna was released from the membrane later in infection as the result of formation of the phage head; detachment of the dna required the action of gene products 20, 21, 22, 23, 24, 31, 16, 17 and 49, known to be necessary for normal head formation. gene products 2 ... | 1973 | 4632440 |
| serological relatedness of bacterial deoxyribonucleic acid polymerases. | a number of bacterial species have been surveyed for serological activities with antiserum to escherichia coli b deoxyribonucleic acid (dna) polymerase i (ec 2.7.7.7.). the degree of serological cross-reaction is taken as a measure of relatedness of both the enzyme molecules from various species and the bacterial species themselves. extracts were assayed by complement fixation only after treatment with deoxyribonuclease, since dna bound to dna polymerase alters the serological activity of the en ... | 1973 | 4630512 |
| use of a clonal line of porcine kidney cell cultures for primary isolation and vaccine studies with adenoviruses. | the clonal line (y15) of porcine kidney stable cells provided a recovery system for adenovirus t4 from specimens from adults with respiratory illnesses that was as sensitive as human embryo kidney cultures. adenoviruses t7 from adults, and t1, 2, 3, and 5 from children could be readily isolated in porcine kidney cell cultures. the latter were useful for adenovirus vaccine studies in that infectivity titers of live virus vaccine and neutralization antibody responses after vaccination were equal t ... | 1972 | 4629702 |
| human prolactin and thyrotropin concentrations in the serums of normal and hypopituitary children before and after the administration of synthetic thyrotropin-releasing hormone. | synthetic thyrotropin-releasing hormone (trh) was administered to normal children and hypopituitary patients in a dose of 7 mug/kg i.v. over 30-60 sec. serum thyrotropin (tsh) and prolactin (hpr) concentrations were measured by radioimmunoassay before and at 15-min intervals for 2 hr after trh. in 20 normal children hpr rose from a mean baseline value of 7.0+/-1.2 (sem) ng/ml to a mean peak value of 39.5+/-5 ng/ml. in 11 patients with growth hormone (gh) deficiency without tsh deficiency. hpr va ... | 1972 | 4626583 |

| metabolism of t4 bacteriophage ghost-infected cells. ii. do ghosts cause a generalized permeability change? | ghosts appear to alter the barrier function of the cell membrane, allowing the release of phosphorylated sugars which normally cannot pass through the cell membrane, whereas phage do not. no increased influx of normally impermeable compounds is observed in the presence of ghosts, indicating that the loss of membrane function after ghost infection cannot be attributed to a generalized breakdown of the permeability barrier. | 1972 | 4624785 |
| effect of nalidixic acid on the growth of deoxyribonucleic acid bacteriophages. | the effect of nalidixic acid on the growth of various deoxyribonucleic acid (dna) bacteriophages has been investigated by one-step growth experiments. the escherichia coli bacteriophages t5, lambda, t7 and phir are strongly inhibited by nalidixic acid, whereas t4 and t2 are only partially inhibited. the bacillus subtilis bacteriophages sp82, sp50, and phi29 are relatively unaffected by nalidixic acid. there is no correlation between those bacteriophages which can grow in the presence of nalidixi ... | 1972 | 4621668 |

| phospholipase a-deficient mutants of escherichia coli b. | phospholipase a-deficient mutants were isolated from escherichia coli b/sm as follows. replica plates were incubated to allow formation of colonies and then overlayed with soft agar containing washed sheep erythrocytes, lecithin ca++, colistin, lysozyme and streptomycin. the mutant colonies were detected as colonies without hemolytic zones. two or three cycles of treatment with mutagen and selection were necessary for their isolation. the mutants obtained could grow in a synthetic medium with g ... | 1974 | 4619011 |
