Sysname
riboflavin:NAD(P)+ oxidoreductase
Reaction(IUBMB)
reduced riboflavin + NAD(P)+ = riboflavin + NAD(P)H + H+ [RN:
R05707 R09750 ]
Reaction(KEGG)
Substrate
Product
Comment
Catalyses the reduction of soluble flavins by reduced pyridine nucleotides. Highest activity with riboflavin. When NADH is used as acceptor, the enzyme can also utilize FMN and FAD as substrates, with lower activity than riboflavin. When NADPH is used as acceptor, the enzyme has a very low activity with FMN and no activity with FAD [1].
