Polarized injection of the bacteriophage T5 chromosome.
Examination of the first-step-transfer DNA of T5ris mutants which carry new EcoRI sites showed that the left end of the chromosome is injected first.
متن کاملGenetic suppressors of bacteriophage t5 amber mutants.
Nonsense mutations in structural genes appear to abort polypeptide chain synthesis at the amino acid site governed by the mutant codon. The two presently recognized types of nonsense mutant, amber and ochre, have been assigned the codons UAG and UAA, respectively. Certain bacteria harbor one or more genetic suppressors that counteract the effect of appropriate nonsense mutations in their own st...
متن کاملAlteration of the Escherichia coli membrane by addition of bacteriophage T4 protein synthesized after infection.
Many T4-induced proteins were found associated with the Escherichia coli membrane during infection. Some of these were apparently ionically bound, but many could be identified as integral parts of the inner and outer bacterial membranes by their selective solubilities in guanidine or Sarkosyl. The synthesis and insertion of these proteins into the bacterial membrane were temporally controlled a...
متن کاملFluorescence changes of a membrane-bound dye during bacteriophage T5 infection of Escherichia coli.
The fluorescence intensity of membrane-bound N-phenyl-1-naphthylamine increases dramatically when T5 bacteriophage infect colicin Ib plasmid-containing hosts. This dramatic increase is not seen during normal infections or in infections wherein either the plasmid or the phage contain mutations which allow productive infection to occur. Two smaller increases in fluorescence intensity are seen, ho...
متن کاملRole of the T5 gene D15 nuclease in the generation of nicked bacteriophage T5 DNA.
The processing of newly replicated concatameric T5 DNA into both single stranded DNA changed of unit length and single-stranded fragments of sizes comparable to those found in mature T5 virion DNA occurs in the absence of late T5 protein synthesis. The formation of unit-length, single-stranded DNA chains does not require the early T5 gene D15 nuclease: however, the subsequent formation of the s...
