Both NAD + and NADH strongly absorb ultraviolet light because of the adenine. For example, peak absorption of NAD + is at a wavelength of 259 nanometers (nm), with an extinction coefficient of 16,900 M −1 cm −1. NADH also absorbs at higher wavelengths, with a second peak in UV absorption at 339 nm with an extinction coefficient of 6,220 M ...
Thus, the two substrates of this enzyme are succinate and NAD +, whereas its three products are fumarate, NADH, and H +. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is succinate:NAD+ oxidoreductase.
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').
The systematic name of this enzyme class is ATP:NADH 2'-phosphotransferase. Other names in common use include reduced nicotinamide adenine dinucleotide kinase (phosphorylating) , DPNH kinase , reduced diphosphopyridine nucleotide kinase , and NADH kinase .
Cytosolic Glycerol-3-phosphate dehydrogenase (GPD1), is an NAD+-dependent enzyme [8] that reduces dihydroxyacetone phosphate to glycerol-3-phosphate. Simultaneously, NADH is oxidized to NAD+ in the following reaction: GPD1 Reaction Mechanism. As a result, NAD+ is regenerated for further metabolic activity.
The Rossmann fold is a tertiary fold found in proteins that bind nucleotides, such as enzyme cofactors FAD, NAD +, and NADP +.This fold is composed of alternating beta strands and alpha helical segments where the beta strands are hydrogen bonded to each other forming an extended beta sheet and the alpha helices surround both faces of the sheet to produce a three-layered sandwich.
This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with NAD+ or NADP+ as acceptor. The systematic name of this enzyme is NADPH:NAD+ oxidoreductase (Si-specific). Other names in common use include non-energy-linked transhydrogenase, NAD(P)+ transhydrogenase (B-specific), and soluble transhydrogenase.
In enzymology, a NAD + diphosphatase (EC 3.6.1.22) is an enzyme that catalyzes the chemical reaction. NAD + + H 2 O AMP + NMN. Thus, the two substrates of this enzyme are NAD + and H 2 O, whereas its two products are AMP and NMN.
