Term
oxidoreductase
Definition
involved in oxidation-reduction reaction
Term
dehydrogenase
Definition
transfers electrons and hydrogens from donor to another molecule
(alcohol + NAD+ --> aldehyde + NADH + H+)
Term
oxidase
Definition
transfers electrons and hydrogens from donor to oxygen (--> H2O2)
Term
transferase
Definition
transfers part of one molecule to another
(X-Y + Z <-- --> X + Y-Z)
Term
hydrolase
Definition
cleavage of bonds with the addition of water;
cleaves C-O, C-C, C-N, etc.
The donor group is transferred to water
Term
lyase
Definition
cleaves C-O, C-C, C-N, leaving double bonds or adding groups to double bonds
Term
isomerase
Definition
changes geometric or spatial configuration of a molecule

ex: epimerase, recemase, mutase
Term
ligase or synthetase
Definition
uses the energy derived form the hydrolysis of a high energy bond (ATP) to join 2 molecules
Term
kinase
Definition
adds a phosphate group (PO3) to a molecule; generally obtains the phosphate from ATP
Term
phosphatase
Definition
removes a phosphate group from a molecule
