fmnh 2 + nad(p)+ fmn + nad(p)h + h + The 3 substrates of this enzyme are FMNH2 , NAD + , and NADP + , whereas its 4 products are FMN , NADH , NADPH , and H + . This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor.
NADPH first transfers a hydride equivalent to FAD, creating FADH −, and then NADP + dissociates from the enzyme. Reduced PHBH then reacts with molecular oxygen to form the flavin-C(4a)-hydroperoxide. The flavin hydroperoxide quickly hydroxylates pOHB, and then eliminates water to regenerate oxidized flavin. [23]
FMN reductase (NAD(P)H) (EC 1.5.1.39, FRG) is an enzyme with systematic name FMNH 2:NAD(P) + oxidoreductase. [1] This enzyme catalyses the following chemical reaction FMNH2 + NAD(P) + ⇌ {\displaystyle \rightleftharpoons } FMN + NAD(P)H + H +
FMNH 2 is then oxidized in two one-electron steps, through a semiquinone intermediate. Each electron thus transfers from the FMNH 2 to an Fe–S cluster , from the Fe-S cluster to ubiquinone (Q). Transfer of the first electron results in the free-radical ( semiquinone ) form of Q, and transfer of the second electron reduces the semiquinone form ...

NADP is a reducing agent in anabolic reactions like the Calvin cycle and lipid and nucleic acid syntheses. NADP exists in two forms: NADP+, the oxidized form, and NADPH, the reduced form. NADP is similar to nicotinamide adenine dinucleotide (NAD), but NADP has a phosphate group at the C-2′ position of the adenosyl
