FMN reductase (NADPH) activity
Definition
Target type: molecularfunction
Catalysis of the reaction: FMNH2 + NADP+ = FMN + NADPH + 2 H+. [RHEA:21624]
FMN reductase (NADPH) activity catalyzes the transfer of electrons from NADPH to flavin mononucleotide (FMN). This reaction is essential for a wide range of cellular processes, including the reduction of oxidized glutathione, the biosynthesis of fatty acids, and the detoxification of reactive oxygen species. The enzyme utilizes NADPH as a reducing agent, transferring a hydride ion to FMN, which is then reduced to FMNH2. This reduced form of FMN can then be used in a variety of downstream reactions. For example, FMNH2 can donate electrons to other proteins involved in electron transport chains, or it can be used to reduce specific substrates, such as oxidized glutathione or molecular oxygen.'
