A new gene, mutK, of Vibrio cholerae, encoding a 19-kDa protein which is involved in repairing mismatches in DNA via a presumably methyl-independent pathway, has been identified. The product of the mutK gene cloned in either high- or low-copy-number vectors can reduce the spontaneous mutation frequency of Escherichia coli mutS, mutL, mutU, and dam mutants.(More)
