Glyceraldehyde 3-phosphate dehydrogenase (abbreviated GAPDH) (EC 1.2.1.12) is an enzyme of about 37kDa that catalyzes the sixth step of glycolysis and thus serves to break down glucose for energy and carbon molecules.
This gene encodes a protein belonging to the glyceraldehyde-3-phosphate dehydrogenase family of enzymes that play an important role in carbohydrate metabolism.Like its somatic cell counterpart, this sperm-specific enzyme functions in a nicotinamide adenine dinucleotide-dependent manner to remove hydrogen and add phosphate to glyceraldehyde 3-phosphate to form 1,3-diphosphoglycerate.
The NADPH and 3-PG can then be used for synthesis. The most familiar variant of glycolysis uses glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoglycerate kinase to produce ATP. GAPDH is phosphorylating. GAPN is non-phosphorylating. GAPN was reported first by Rosenberg and Arnon in 1954. [1] It has been found in plants, algae, and ...
Glyceraldehyde-3-phosphate-dehydrogenase is a cellular enzyme typically involved in glycolysis. GAPDH is known to bind to the overlapping sites within the stem-loop IIIa within the HAV IRES. The stem-loop IIIa contains a UU nucleotide deletion inside of a 5 nucleotide sequence which enhances the IRES activity. GAPDH effectively binding to this ...
Chemical structure of 1-arseno-3-phosphoglycerate. 1-Arseno-3-phosphoglycerate is a compound produced by the enzyme glyceraldehyde 3-phosphate dehydrogenase, present in high concentrations in many organisms, from glyceraldehyde 3-phosphate and arsenate in the glycolysis pathway. [1]
The glycolytic enzyme, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), is responsible for the oxidative conversion of glyceraldehyde-3-phosphate (GADP) to 1,3-bisphosphoglycerate (1,3BPG). Up-regulation of glyceraldehyde-3-phosphate dehydrogenase expression is maximal (4-5 fold) following hypoxic conditions of ~24 hours in vascular ...
