The gene encoding component S, the small subunit, of glutamate mutase, an adenosylcobalamin (coenzyme B12)-dependent enzyme from Clostridium tetanomorphum has been cloned and its nucleotide sequence determined. The mutS gene encodes a protein of 137 amino acid residues, with M(r) 14,748. The deduced amino acid sequence showed homology with the C-terminal portion of adenosylcobalamin-dependent methylmalonyl-CoA mutase [1989, Biochem. J. 260, 345-352] and a region of cobalamin-dependent methionine synthase which has been shown to bind cobalamin [1989, J. Biol. Chem 264, 13888-13895].
