ENZYME entry: EC

Accepted Name
Riboflavin reductase (NAD(P)H).
Alternative Name(s)
Flavin mononucleotide reductase.
Flavine mononucleotide reductase.
NAD(P)H(2) dehydrogenase (FMN).
NAD(P)H-dependent FMN reductase.
Riboflavin mononucleotide reductase.
Riboflavine mononucleotide reductase.
Reaction catalysed
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 and EC
