Protein

Enolase

Gene

eno

Organism
Chloroherpeton thalassium (strain ATCC 35110 / GB-78)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis.UniRule annotation

Catalytic activityi

2-phospho-D-glycerate = phosphoenolpyruvate + H2O.UniRule annotation

Cofactori

Mg2+UniRule annotation

Enzyme regulationi

The covalent binding to the substrate causes inactivation of the enzyme, and possibly serves as a signal for the export of the protein.UniRule annotation

Pathwayi: glycolysis

This protein is involved in step 4 of the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate.UniRule annotation
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Phosphoglycerate kinase (pgk)
  3. 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA)
  4. Enolase (eno)
  5. Pyruvate kinase (Ctha_1959)
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.

Subcellular locationi

  • Cytoplasm UniRule annotation
  • Secreted UniRule annotation
  • Cell surface UniRule annotation
  • Note: Fractions of enolase are present in both the cytoplasm and on the cell surface. The export of enolase possibly depends on the covalent binding to the substrate; once secreted, it remains attached to the cell surface.UniRule annotation
