The mmsA locus of Streptococcus pneumoniae encodes a RecG-like protein involved in DNA repair and in three-strand recombination.

Abstract excerpt

We describe the characterization of a mutant strain of Streptococcus pneumoniae previously isolated on the basis of its sensitivity to Methyl Methane Sulphonate (MMS). The mutant strain also exhibited increased sensitivity to UV light and to X-rays, together with a reduced capacity for recombination and Hex-mediated generalized mismatch repair. We show that the original mutant contains two unlinked mutations in...
