Flavin adenine dinucleotide consists of two portions: the adenine nucleotide (adenosine monophosphate) and the flavin mononucleotide (FMN) bridged together through their phosphate groups. Adenine is bound to a cyclic ribose at the 1' carbon, while phosphate is bound to the ribose at the 5' carbon to form the adenine nucledotide.
The three substrates of this enzyme are NADPH, H +, and oxidized hemoprotein, whereas its two products are NADP + and reduced hemoprotein. It has two cofactors: flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a heme protein ...
Nicotinamide adenine dinucleotide phosphate, abbreviated NADP [1] [2] or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent ('hydrogen source'). NADPH is the reduced form, whereas NADP + is the ...
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
Flavoproteins have either FMN (flavin mononucleotide) or FAD (flavin adenine dinucleotide) as a prosthetic group or as a cofactor. The flavin is generally tightly bound (as in adrenodoxin reductase, wherein the FAD is buried deeply). [1] About 5-10% of flavoproteins have a covalently linked FAD. [2]
A bond angle is the angle formed between three atoms across at least two bonds. For four atoms bonded together in a chain, the torsional angle is the angle between the plane formed by the first three atoms and the plane formed by the last three atoms. There exists a mathematical relationship among the bond angles for one central atom and four ...

Flavin reductases are similar and often confused for ferric reductases because of their similar catalytic mechanism and structures. [4] In enzymology, a flavin reductase (EC 1.5.1.30) is an enzyme that catalyzes the chemical reaction. riboflavin + NADPH + H + reduced riboflavin + NADP + H +
