ID   1.5.1.41
DE   riboflavin reductase [NAD(P)H].
AN   flavine mononucleotide reductase.
AN   flavin mononucleotide reductase.
AN   NAD(P)H2 dehydrogenase (FMN).
AN   NAD(P)H-dependent FMN reductase.
AN   riboflavine mononucleotide reductase.
AN   riboflavin mononucleotide reductase.
CA   (1) NAD(+) + reduced riboflavin = 2 H(+) + NADH + riboflavin.
CA   (2) NADP(+) + reduced riboflavin = 2 H(+) + NADPH + riboflavin.
CC   -!- Catalyzes the reduction of soluble flavins by reduced pyridine
CC       nucleotides.
CC   -!- Highest activity with riboflavin.
CC   -!- When NADH is used as acceptor, the enzyme can also utilize FMN and
CC       FAD as substrates, with lower activity than riboflavin.
CC   -!- When NADPH is used as acceptor, the enzyme has a very low activity
CC       with FMN and no activity with FAD.
CC   -!- Formerly EC 1.5.1.29 and EC 1.6.8.1.
