Abstract
PKM101, a plasmid R factor of the N compatibility group increases methylmethane sulfonate mutagenesis and diminishes UV-killing in recA + lex + and recA + lex − strains, but not in recA − lex + strains. The induction of a “reclex” dependent colicin is not present in lex − strains carrying the pKM101 factor. These facts indicate that pKM101 acts through an error-prone DNA repair system, which is recA + dependent, but not lex + dependent.This publication has 18 references indexed in Scilit:
