Ant-mediated transactivation of early genes in Salmonella prophage P22 by superinfecting virulent P22 mutants.

H H Prell.   

Abstract

The virulent mutants P22 virB vy and P22 vy mutants, both insensitive to mnt-repressor, transactivate the early genes of a P22 prophage. The transactivation of early P22 prophage genes depends strictly on the expression of gene ant ("antirepressor"-protein) by the superinfecting P22 mutant and therefore occurs by derepression.
