Transport in bacteriophage P22-infected Salmonella typhimurium.
There was rapid efflux of L-leucine, L-phenylalanine, and alpha-methyl-D-glucoside after infection of Salmonella typhimurium with the clear plaque mutant C1 of phage P22. The efflux was similar to that observed with cyanide or arsenate treatment except that there was partial recovery in the case of phage infection and almost complete recovery under the condition of lysogeny. There was no efflux...
متن کاملTransduction by bacteriophage P22 in nonsmooth mutants of Salmonella typhimurium.
The general transducing phage P22 attacks only smooth (S) Salmonella with O antigen 12, determined by the oligosaccharide repeating unit constituting the distal part of the somatic lipopolysaccharide (LPS) side chain; non-S mutants, whose LPS contain few or no O repeating units, appear to be resistant. Auxotrophic non-S mutants of Salmonella typhimurium LT2 were tested as transductional recipie...
متن کاملPatterns of transcription in bacteriophage P22-infected Salmonella typhimurium.
Two peaks of RNA synthesis (early and late) are directed by bacteriophage P22 in lytic infections of Salmonella typhimurium. Late RNA synthesis is not seen in P22 23- infections; neither early nor late RNA synthesis occurs in P22 24- infections. Genes 23 and 24 of P22 appear to be analogous to genes Q and N of lambda, respectively.
متن کاملHost transcription in bacteriophage P22-infected Salmonella typhimurium.
The kinetics of host RNA synthesis, as measured by pulse-label kinetics and RNA-DNA hybridization, is inhibited 10-fold shortly after infection with bacteriophage P22. This early inhibition lasts through the first 6 min of infection and affects not only RNA synthesis but several other energy-requiring cellular functions. In lysogenic infections, the rate of bacterial transcription rapidly recov...
متن کاملGeneralized transduction by bacteriophage P22 in Salmonella typhimurium. II. Mechanism of integration of transducing DNA.
Generalized transduction by bacteriophage P22 occurs by the transfer of DNA from one bacterium to another by means of a phage-like particle (i.e. a transducing particle) which contains bacterial DNA formed before infection (preceding paper). Transduction of a 3aP-labeled, light recipient with purified transducing particles whose DNA is labeled with 3H, zH, 16N, 13C results in the physical assoc...
