Metilamin-korinoid protein Co-metiltransferaza (EC 2.1.1.248, mtmB (gen), monometilaminska metiltransferaza) je enzim sa sistematskim imenom monometilamin:5-hidroksibenzimidazolilkobamid Co-metiltransferaza.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- metilamin + [Co(I) metilamin-specifični korinoidni protein] [metil-Co(III) metilamin-specifični korinoidni protein] + amonijak
Enzim koji katalizuje transfer metil grupa sa metilamina na metilamin-specifični korinoidni protein (MtmC), učestvuje u metanogenezi. Ovaj enzim sadrži neobičnu aminokiselinu pirolizin.
