Interaction of Escherichia coli RecA protein with LexA repressor. II. Inhibition of DNA strand exchange by the uncleavable LexA S119A repressor argues that recombination and SOS induction are competitive processes

The Escherichia coli RecA protein is involved in SOS induction, DNA repair, and homologous recombination. In vitro, RecA protein serves as a co-protease to cleave LexA repressor, the repressor of the SOS regulon; in addition, RecA protein promotes homologous pairing and DNA strand exchange, steps im...
