The Escherichia coli Mismatch Repair Protein MutL Recruits the Vsr and MutH Endonucleases in Response to DNA Damage

摘要

The activities of the Vsr and MutH endonucleases of Escherichia coli are stimulated by MutL. The interaction of MutL with each enzyme is enhanced in vivo by 2-aminopurine treatment and by inactivation of the mutY gene. We hypothesize that MutL recruits the endonucleases to sites of DNA damage.
