CC   -!- FUNCTION: Acts probably as a methyl group carrier between MttB and
CC       either MtbA or MtaA. {ECO:0000250}.
CC   -!- PATHWAY: One-carbon metabolism; methanogenesis from trimethylamine.
CC   -!- SUBUNIT: Can form a complex with MttB. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the methylamine corrinoid protein family.
CC       {ECO:0000305}.
