ENZYME entry: EC

Accepted Name
glycine betaine--corrinoid protein Co-methyltransferase.
Alternative Name(s)
glycine betaine methyltransferase.
Reaction catalysed
Co(I)-[glycine betaine-specific corrinoid protein] + glycine betaine + H(+) <=> methyl-Co(III)-[glycine betaine-specific corrinoid protein] + N,N-dimethylglycine
  • The enzyme, which catalyzes the transfer of a methyl group from glycine betaine to a glycine betaine-specific corrinoid protein (MtgC), is involved in methanogenesis from glycine betaine in some methanogenic archaea, and in glycine betaine degradation in some bacteria.
  • Unlike similar enzymes involved in methanogenesis from methylated C1 compounds, this enzyme does not contain the unusual amino acid L-pyrrolysine.
