Comments [?]

Function Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis.
Catalytic activity 2-phospho-D-glycerate = phosphoenolpyruvate + H(2)O.
case <FTGroup:1>
Cofactor Mg(2+)
end case
case <FTTag:inhib>
Enzyme regulation The covalent binding to the substrate causes inactivation of the enzyme, and possibly serves as a signal for the export of the protein.
end case
Pathway Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 4/5.
case <OC:Gammaproteobacteria>
Subunit Component of the RNA degradosome, which is a multiprotein complex involved in RNA processing and mRNA degradation.
end case
Subcellular location Cytoplasm. Secreted. Cell surface. 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.
Similarity Belongs to the enolase family.
