WebEnolase extracts a water molecule from 2-Phosphoglycerate to yield Phosphoenolpyruvate (normal humans usually call this PEP, I wouldn't try pronouncing any of these crazy words) during glycolysis. It arranges the molecule in a way where the PEP becomes very unstable. ... Yes, glycolysis is the energy yielding (ATP producing) part of ... Phosphopyruvate hydratase, usually known as enolase, is a metalloenzyme (EC 4.2.1.11) that catalyses the conversion of 2-phosphoglycerate (2-PG) to phosphoenolpyruvate (PEP), the ninth and penultimate step of glycolysis. The chemical reaction is: 2-phospho-D-glycerate See more In humans there are three subunits of enolase, α, β, and γ, each encoded by a separate gene that can combine to form five different isoenzymes: αα, αβ, αγ, ββ, and γγ. Three of these isoenzymes (all homodimers) are … See more Using isotopic probes, the overall mechanism for converting 2-PG to PEP is proposed to be an E1cB elimination reaction involving a carbanion intermediate.
