Protein

Pyruvate kinase

Gene

pyk

Organism
Staphylococcus aureus (strain Mu50 / ATCC 700699)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalytic activityi

ATP + pyruvate = ADP + phosphoenolpyruvate.

Cofactori

Protein has several cofactor binding sites:
  • Mg2+By similarity
  • K+By similarity

Pathwayi: glycolysis

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 1 (gapA1), Glyceraldehyde-3-phosphate dehydrogenase 2 (gapA2)
  2. Phosphoglycerate kinase (pgk)
  3. 2,3-bisphosphoglycerate-independent phosphoglycerate mutase (gpmI), 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA)
  4. Enolase (eno)
  5. Pyruvate kinase (pyk)
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.
