oxidoreductase activity, acting on the CH-NH group of donors, NAD or NADP as acceptor riboflavin reductase [NAD(P)H] activity https://github.com/geneontology/go-ontology/issues/16166 RHEA:31455 riboflavin mononucleotide reductase activity molecular_function Catalysis of the reaction: reduced riboflavin + NAD(P)+ = riboflavin + NAD(P)H + 2 H+. This reaction can utilize NADH and NADPH. riboflavin reductase (NADH) activity NAD(P)H2 dehydrogenase (FMN) activity riboflavin reductase (NADPH) activity EC:1.5.1.41 NAD(P)H:FMN oxidoreductase activity NAD(P)H:riboflavin oxidoreductase activity MetaCyc:RXN-12445 riboflavin mononucleotide (reduced nicotinamide adenine dinucleotide) reductase activity GO:0052875 NAD(P)H-FMN reductase activity flavine mononucleotide reductase activity KEGG_REACTION:R09750 NAD(P)H-dependent FMN reductase activity flavin mononucleotide reductase activity riboflavine mononucleotide reductase activity NAD(P)H2:FMN oxidoreductase activity
