Chains	Enzyme Name	Description	Catalytic Residues
A	2-dehydro-3-deoxy-phosphogluconate aldolase M-CSA #550	2-ket-3-deoxy-phosphogluconate (KDPG) aldolase is a Class I aldolase of the glycolytic pathway. It catalyses the reversible cleavage of KDPG into the three carbon units pyruvate and glyceraldehyde-3-phosphate. The enzymatic aldol reaction is highly efficient, regioselective and shows high facial stereoselectivity. The mechanism shown here is the formation KDGP from pyruvate and glyceraldehyde-3-phosphate.
