Enzymes and Their Functions

Intro to Biology

oxidoreductases

catalyze transfer electrons between molecules

transferases

catalyze the transfer of groups of atoms (functional groups) between molecules

aminotransferases

transfer amino group (-NH2)

kinases

transfer a phosphate group

hydrolases

add water to covalent bonds to break down molecules (hydrolysis)

isomerases

catalyze transfer of groups from one place to another within the same molecule

ligases

catalyze joining of two molecules together

lyases

catalyze non-hydrolytic breakage of bonds in molecules

phosphatases

catalyze the removal of phosphate group from proteins

phosphodiesterases

catalyze the removal of phosphate group from proteins

GTPase

catalyze hydrolysis of GTP

ATPase

catalyze hydrolysis of ATP
