Table 2. Classification of the Main Industrial Enzymes and Their Examples and Reactions.

enzyme class	types of reactions catalyzed	enzymes
hydrolases	hydrolysis of molecules and degradation in some cases	cellulase, protease, amylase, lipase
lyases	nonhydrolytic cleavage of degradation of the molecule	fumarase
transferases	transfer a group from one molecule to another	transaminase
oxidoreductases	oxidation or reduction of molecules	laccases
isomerases	conversion of one isomer to another	glucosephoshate, isomerase
ligases	joining of two molecules with adenosine triphosphate (atp)	glutamine synthetase
