The reaction rate enhancement that enzymes produce had not been fully appreciated. The object of the article is to present the mechanism of the enormous catalytic power of the enzymes. I conclude that during substrate conversion to product the enzyme transfers firstly some additional small reactant group that must be initially presented in the active site of the enzyme to bound substrate (i) ; the enzyme regenerates during second substrate group transfer (ii); the active enzyme acts as a reactant of the enzymatic reaction (iii). The detailed chemical mechanisms of enzymatic reactions, such as a the well-studied reaction of the serine proteases family, the peptide bond hydrolysis catalyzed by α-chymotrypsin, and the glyceraldehyde-3-phosphate interconversion step in glycolysis, are in accordance with my conclusion.
