Abstract

Phage lambda repressor is inactivated and cleaved into two detectable fragments during incubation with purified Escherichia coli recA gene protein in vitro, in a reaction that requires ATP. This reaction reproduces the recA-dependent inactivation of repressor that occurs in vivo during induction of the SOS functions. The proteolytic activity may reside in the recA protein itself and may be a fundamental activity of it.
