Identification
Name: 2-Phosphoglyceric acid
Description:2-Phosphoglyceric acid (2PGA) is a glyceric acid which serves as the substrate in the ninth step of glycolysis. It is catalyzed by enolase into phosphoenolpyruvate (PEP), the penultimate step in the conversion of glucose to pyruvate. Enolase catalyzes the beta-elimination reaction in a stepwise manner wherein OH- is eliminated from C3 of a discrete carbanion (enolate) intermediate. This intermediate is created by removal of the proton from C2 of 2PGA by a base in the active site. (PMID: 8994873, Wikipedia)
