P22 antirepressor protein prevents in vivo recA-dependent proteolysis of P22 repressor.

Abstract

A method was developed to demonstrate recA-dependent P22-repressor breakdown in vivo by SDS-polyacrylamide electrophoresis of unfractionated extracts of phage-infected, lysogenic Salmonella typhimurium strains TA1530 rec+ and TA1530 recA1-. The antirepressor of P22 is not cleaved by recA protein. Under conditions of unregulated ant-overproduction (Harvey et al. 1981) antirepressor protects c2-repressor in vivo against proteolytic cleavage by recA protein.
