Corrinoid Adenosyltransferase MMAB

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Corrinoid adenosyltransferase MMAB (250 aa, ~27 kDa) is encoded by the human MMAB gene. This protein plays a role in ATP hydrolysis and the conversion of cobalamin (cob(I)alamin) to adenosylcobalamin (adenosylcob(III)alamin).
