ENZYME CLASSIFICATION 1. OXIDOREDUCTASES catalyze oxidation-reduction reactions dehydrogenases, reductases lactate dehydrogenase (NAD + ), acyl CoA dehydrogenase (FAD) , ketoacyl-ACP reductase (NADPH/H + ) 2. TRANSFERASES catalyze functional group transfers kinases, aminotransferases, thiolases glucokinase (ATP), aspartate aminotransferase (PLP), β - ketothiolase 3. HYDROLASES catalyze hydrolysis reactions peptidases, glycosidases, lipases, phosphatases trypsin, amylase, triacylglycerol lipase, fructose-1,6-bisphosphatase 4. LYASES catalyze elimination (or addition) of groups to form (or break)
