Transferases (EC 2)

Enzymes can be classified systematically according to the difference between reaction and substrate specificity, and the mechanism of action. Transferases (EC 2.x.x.x) are a large class of enzymes that catalyse the transfer of a functional group, such as amine, carboxyl, carbonyl, methyl, acyl, glycosyl, and phosphoryl from a donor molecule to an acceptor molecule. Transferases are involved in hundreds of different biochemical pathways throughout biology, and are integral to some of life’s most important processes. Transferases includes: EC 2.1 (e.g. methyltransferase), EC 2.2 (e.g. transketolase), EC 2.3 (e.g. acyltransferase), EC 2.4 (e.g. glycosyltransferase), EC 2.5 (e.g. riboflavin synthase), EC 2.6 (e.g. transaminase), EC 2.7 (e.g. kinases), EC 2.8 (e.g. sulfurtransferase), EC 2.9 (e.g. selenotransferase), and EC 2.10 (e.g. molybdenumtransferase).
