Functioni

Catalytic activityi

ATP + pyruvate = ADP + phosphoenolpyruvate.

Cofactori

Protein has several cofactor binding sites:

Pathway:iglycolysis

This protein is involved in step 5 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 (gapA)
  2. Phosphoglycerate kinase (pgk), Phosphoglycerate kinase (pgk)
  3. 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA), Probable phosphoglycerate mutase GpmB (gpmB), Probable phosphoglycerate mutase GpmB (gpmB), 2,3-bisphosphoglycerate-independent phosphoglycerate mutase (gpmI), 2,3-bisphosphoglycerate-independent phosphoglycerate mutase (gpmI), 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA)
  4. Enolase (eno), Enolase (eno)
  5. Pyruvate kinase (pykF), Pyruvate kinase (pykA), Pyruvate kinase (pykF), Pyruvate kinase (pykA), Pyruvate kinase I (pykF)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.

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 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.
