GAPDH (Glyceraldehyde-3-phosphate dehydrogenase) is well known as one of the key enzymes involved in glycolysis. It catalyzes an important energy-yielding step in carbohydrate metabolism, the reversible o, Xenopus/Amphibian,idative phosphorylation of glyceraldehyde-3-phosphate in the presence of inorganic phosphate and nicotinamide adenine dinucleotide (NAD). The enzyme e, Xenopus/Amphibian,ists as a tetramer of identical chains. Besides its functioning as a glycolytic enzyme in cytoplasm, recent evidence suggest that mammalian GAPDH is also involved in a great number of intracellular processes such as membrane fusion,Mouse,icrotubule bundling,Porcinehosphotransferase activity, nuclear RNA e, Xenopus/Amphibian,port, DNA replication and DNA repair.
