Transcription and translation of prereplicative bacteriophage T4 genes in vitro.
Bacteriophage T4 DNA was used to direct transcription and translation in vitro in extracts prepared from uninfected Escherichia coli. The radioactive protein products of the cell-free reactions were examined on sodium dodecyl sulfate acrylamide gels. We conclude that the cell-free system prepared from uninfected E. coli has the capacity to synthesize most T4 prereplicative RNAs and proteins. Fu...
متن کاملThe bacteriophage T4 rapid-lysis genes and their mutational proclivities.
Like most phages with double-stranded DNA, phage T4 exits the infected host cell by a lytic process requiring, at a minimum, an endolysin and a holin. Unlike most phages, T4 can sense superinfection (which signals the depletion of uninfected host cells) and responds by delaying lysis and achieving an order-of-magnitude increase in burst size using a mechanism called lysis inhibition (LIN). T4 r...
متن کاملBacteriophage T4 genes sp and 40 apparently are the same.
The bacteriophage T4 spackle gene, which maintains host membrane integrity, mapped at the same position as gene 40 (head morphogenesis). The cloned spackle gene complemented and cross-reactivated a gene 40 mutant. Like the spackle mutant, gene 40 mutants were defective in genetic exclusion. Apparently, genes spackle and 40 are the same gene.
متن کاملMisrepair mutagenesis in bacteriophage T4.
The T4 mutations px, y and 1206 inactivate an error-prone recombination-like repair system, reducing or abolishing mutagenesis by UV irradiation, MMS, and white light irradiation in the presence of the photosensitizer 8MOP. Both px and y increase some spontaneous mutation rates and slightly enhance proflavin mutagenesis; neither mutation affects thymineless or 2AP mutagenesis appreciably, but b...
متن کاملGenetic control of capsid length in bacteriophage T4: phenotypes displayed by ptg mutants.
The phenotypic characteristics of 26 ptg mutations in T4 gene 23 are described. All were located in three tight clusters in that gene and, by definition of ptg mutations, all produced giant phage. Intermediate petite phage, which invariably made up a substantial fraction of the progeny of these mutants, appeared to be a unique product of gene 23 mutations. Isometric petite phage were produced i...
