Nucleotide sequence of the Escherichia coli micA gene required for A/G-specific mismatch repair: identity of micA and mutY.

Abstract excerpt

The Escherichia coli methylation-independent repair pathway specific for A/G mismatches has been shown to require the gene product of micA. Extracts prepared from micA mutants do not form an A/G mismatch-specific DNA-protein complex and do not contain an A/G mismatch-specific nicking activity. Moreover, a partially purified protein fraction containing both A/G mismatch-specific nicking and binding activities...
