Names

Accepted name:
riboflavin reductase [NAD(P)H]
Other names:

NAD(P)H:flavin oxidoreductase
NAD(P)H2 dehydrogenase (FMN) [ambiguous]
NAD(P)H2:FMN oxidoreductase [ambiguous]
riboflavin mononucleotide reductase [ambiguous]
flavine mononucleotide reductase [ambiguous]

Fre
Systematic name:
riboflavin:NAD(P)+ oxidoreductase

Reaction

Comments:

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].
