Enzyme Information
| 1.5.1.41 |
Riboflavin reductase (NAD(P)H).
based on mapping to UniProt P0AEN1
Reduced riboflavin + NAD(P)(+) = riboflavin + NAD(P)H.
-!- Catalyzes 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. -!- Formerly EC 1.5.1.29 and EC 1.6.8.1.
