About Enolase

Enolase is an enzyme from Lyase family (EC 4.2.1.11), with molecular weight within 40-50kDa range for monomer (biological structure - dimer), that catalyze conversion of 2-phosphoglycerate to phosphoenolpyruvate (PEP) with subsequent removing of water molecule. The overall reaction can be written as 2-Phosphoglycerate <=> Phosphoenolpyruvate + H₂O

Systematic name for Enolase is 2-phospho-D-glycerate hydro-lyase (phosphoenolpyruvate-forming), but in literature other names are also acceptable: 14-3-2-protein; phosphoenolpyruvate hydratase; 2-phosphoglycerate dehydratase; 2-phosphoglycerate dehydratase; nervous-system specific enolase; 2-phosphoglycerate enolase; 2-phospho-D-glycerate hydro-lyase; 2-phosphoglyceric dehydratase and γ-enolase.
