Functioni

Catalytic activityi

ATP + 3-phospho-D-glycerate = ADP + 3-phospho-D-glyceroyl phosphate.

Pathwayi: glycolysis

This protein is involved in step 2 of the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Glyceraldehyde-3-phosphate dehydrogenase, cytosolic, Glyceraldehyde-3-phosphate dehydrogenase, glycosomal
  2. Phosphoglycerate kinase, cytosolic, Phosphoglycerate kinase A, Phosphoglycerate kinase A, Phosphoglycerate kinase, glycosomal, Phosphoglycerate kinase, cytosolic
  3. no protein annotated in this organism
  4. no protein annotated in this organism
  5. Pyruvate kinase 1 (PYK1), Pyruvate kinase 2 (PYK2)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate, the pathway glycolysis and in Carbohydrate degradation.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
