The three substrates of this enzyme are D-glyceraldehyde 3-phosphate, phosphate (Pi), and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are 1,3-bisphosphoglyceric acid, reduced NADPH, and a proton.[1][2][3][4]

Function

This 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

The 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)
