Glyceraldehyde 3-phosphate

Federal government websites often end in, glyceraldehyde 3-phosphate. The site is secure. Glyceraldehydephosphate dehydrogenase GAPDH is a glycolytic enzyme whose role in cell metabolism and homeostasis is well defined, while its function in pathologic processes needs further elucidation.

In addition to this long established metabolic function, GAPDH has recently been implicated in several non-metabolic processes, including transcription activation, initiation of apoptosis , [4] ER-to-Golgi vesicle shuttling , and fast axonal, or axoplasmic transport. This form is composed of four identical kDa subunits containing a single catalytic thiol group each and critical to the enzyme's catalytic function. GAPDH is encoded by a single gene that produces a single mRNA transcript with 8 splice variants, though an isoform does exist as a separate gene that is expressed only in spermatozoa. Enzyme 1. GAPDH uses covalent catalysis and general base catalysis to decrease the very large activation energy of the second step phosphorylation of this reaction. First, a cysteine residue in the active site of GAPDH attacks the carbonyl group of G3P, creating a hemithioacetal intermediate covalent catalysis.

It is an important metabolic intermediate in several central metabolic pathways in all organisms. Although GAPDH1 can contribute to NADPH production, it does not make as much effect on fatty acid synthesis as either malic enzyme or the phosphate pentose glyceraldehyde 3-phosphate, which increase lipid content by 1. Glucose 6-phosphate.

D-glyceraldehyde 3-phosphate is formed from the following three compounds in reversible reactions:. Enzyme 4. The numbering of the carbon atoms indicates the fate of the carbons according to their position in fructose 6-phosphate. Enzyme 5. Enzyme 1. D-glyceraldehyde 3-phosphate is also of some importance since this is how glycerol as DHAP enters the glycolytic and gluconeogenic pathways. Furthermore, it is a participant in and a product of the pentose phosphate pathway.

During plant photosynthesis , 2 equivalents of glycerate 3-phosphate GP; also known as 3-phosphoglycerate are produced by the first step of the light-independent reactions when ribulose 1,5-bisphosphate RuBP and carbon dioxide are catalysed by the rubisco enzyme. RuBP is regenerated for the Calvin cycle to continue.

Glyceraldehydephosphate dehydrogenase GAPDH as an important participant of pathological processes. D is dilution factor. Goasdoue K. Blatnik M. This leads to the opening of permeability transition pores PTPs and to the depolarization of the mitochondria, as well as to the release of cytochrome C and of an apoptosis-inducing factor [ 58 ]. The hemithioacetal is deprotonated by a histidine residue in the enzyme's active site general base catalysis. The achieved data were analyzed with GraphPad Prism 6. Delport A.
