'''Flavin reductase''' (FR) catalyzes the NADPH-dependent reduction of a variety of flavins such as riboflavin, FAD, FMN, biliverdin, methemoglobin and pyrroloquinoline quinone. FR converts reduced riboflavin to riboflavin and bilirubin to biliverdin.  FR is involved in heme catabolism<ref>PMID:7400118</ref> .
