Name | mismatch repair |
Type | SYSTEM |
Description | The combination of MutS (the MutS1 branch but not the MutS2 branch of the MutS family) and MutL leads to a general mechanism for mismatch exision and repair (MMR). Other proteins, recruited by MutS1 and MutL, act to clip (MutH or other endonuclease), remove (UvrD), and resynthesize one strand in the region containing the mismatch. MMR constrasts in its generality with the targeting of specific mismatches by various base excision repair (BER) glycosylases and with variants of MMR that act on specific mismatches. In Escherichia coli and related species that contain the endonuclease MutH and the DNA adenine methylation protein Dam, lack of methylation marks the newly synthesized strand; the mismatch is resolved by excision, removal, and resynthesis of a piece of that strand. MMR is referred to as methyl-directed mismatch repair in this subset of species with MMR. |
