IntEnz Enzyme Nomenclature
EC 1.16.8.1

Names

Accepted name:
cob(II)yrinic acid a,c-diamide reductase
Other name:
cob(II)yrinic acid-a,c-diamide:FMN oxidoreductase [incorrect]
Systematic name:
cob(I)yrinic acid-a,c-diamide:FMN oxidoreductase

Reaction

Comments:

This enzyme also catalyses the reduction of cob(II)yric acid, cob(II)inamide, cob(II)inamide phosphate, GDP-cob(II)inamide and cob(II)alamin although cob(II)yrinic acid a,c-diamide is thought to be the physiological substrate [1]. Also uses FAD and NADH but not NADPH.
