Protein

Putative glyceraldehyde-3-phosphate dehydrogenase C

Gene

gapC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein uncertaini

Functioni

Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.By similarity

Catalytic activityi

D-glyceraldehyde 3-phosphate + phosphate + NAD+ = 3-phospho-D-glyceroyl phosphate + NADH.By similarity

Pathwayi: glycolysis

This protein is involved in step 1 of the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate.Curated
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Putative glyceraldehyde-3-phosphate dehydrogenase C (gapC), Glyceraldehyde-3-phosphate dehydrogenase A (gapA)
  2. Phosphoglycerate kinase (pgk)
  3. Probable phosphoglycerate mutase GpmB (gpmB), 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA), 2,3-bisphosphoglycerate-independent phosphoglycerate mutase (gpmI)
  4. Enolase (eno)
  5. Pyruvate kinase I (pykF), Pyruvate kinase II (pykA)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.

Caution

Could be the product of a pseudogene; in K12 this gene is disrupted by a stop codon and a frameshift. It seems to be intact in a number of wild-type strains.Curated
