Reaction: reduced riboflavin + NADP+ = riboflavin + NADPH + H+
Other name(s): NADPH:flavin oxidoreductase; riboflavin mononucleotide (reduced nicotinamide adenine dinucleotide phosphate) reductase; flavin mononucleotide reductase; flavine mononucleotide reductase; FMN reductase (NADPH); NADPH-dependent FMN reductase; NADPH-flavin reductase; NADPH-FMN reductase; NADPH-specific FMN reductase; riboflavin mononucleotide reductase; riboflavine mononucleotide reductase; NADPH2 dehydrogenase (flavin); NADPH2:riboflavin oxidoreductase
Systematic name: reduced-riboflavin:NADP+ oxidoreductase
Comments: The enzyme from Entamoeba histolytica reduces riboflavin and galactoflavin, and, more slowly, FMN and FAD. NADH is oxidized more slowly than NADPH.
