- D-glyceraldehyde 3-phosphate + phosphate + NADP+ 3-phospho-D-glyceroyl phosphate + NADPH + H+
The 3 substrates of this enzyme are D-glyceraldehyde 3-phosphate, phosphate, and NADP+, whereas its 3 products are 3-phospho-D-glyceroyl phosphate, NADPH, and H+.
Function
editThis enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. This enzyme participates in the Calvin cycle which is an autotrophic carbon fixation pathway.
Nomenclature
editThe systematic name of this enzyme class is D-glyceraldehyde-3-phosphate:NADP+ oxidoreductase (phosphorylating). Other names in common use include:
- dehydrogenase, glyceraldehyde phosphate (nicotinamide adenine dinucleotide phosphate) (phosphorylating)
- GAPDH
- glyceraldehyde phosphate dehydrogenase (nicotinamide adenine dinucleotide phosphate) (phosphorylating)
- glyceraldehyde-3-phosphate dehydrogenase (NADP) (phosphorylating)
- NADP-dependent glyceraldehyde phosphate dehydrogenase
- NADP-glyceraldehyde phosphate dehydrogenase
- NADP-glyceraldehyde-3-phosphate dehydrogenase
- NADP-triose phosphate dehydrogenase
- triosephosphate dehydrogenase (NADP)
