glyceraldehyde-3-phosphate dehydrogenase (NAD+) (non-phosphorylating) activity
Definition
Target type: molecularfunction
Catalysis of the reaction: D-glyceraldehyde 3-phosphate + NAD+ + H2O = 3-phospho-D-glycerate + NADH + H+. [PMID:9497334]
Glyceraldehyde-3-phosphate dehydrogenase (NAD+) (non-phosphorylating) activity catalyzes the reversible oxidation of glyceraldehyde 3-phosphate to 3-phosphoglycerate using NAD+ as an electron acceptor. This reaction is a key step in glycolysis, a metabolic pathway that breaks down glucose to produce ATP. In this non-phosphorylating form, the enzyme does not utilize inorganic phosphate to generate 1,3-bisphosphoglycerate. Instead, it uses NAD+ to oxidize glyceraldehyde 3-phosphate, generating NADH and 3-phosphoglycerate. This reaction is distinct from the canonical glyceraldehyde-3-phosphate dehydrogenase activity, which is phosphorylating and results in the production of 1,3-bisphosphoglycerate. The non-phosphorylating activity is often found in organisms that lack or have reduced levels of the phosphorylating activity. It is also important in certain metabolic pathways, such as the pentose phosphate pathway, where it plays a role in the conversion of glucose 6-phosphate to ribose 5-phosphate.'
