Enzyme Classes

Oxidoreductase

REDOX- transfer of electrons between molecules

Oxidoreductase

Examples: oxidase, reductase, dehydrogenase

Oxidoreductase

Common cofactors: NADH, FADH2, FMN

Transferase

Catalyzes transfer of a functional group b/w molecules

Transferase

Examples: kinase (PO4), transaminase (NH2), phosphate group transfer

Hydrolase

Catalyzes the cutting of bonds with H20

Hydrolase

Examples: maltase(maltose), amylase (amylose), protease (peptide (amide) bonds)

Isomerase

Transfer of an alkyl or functional group within a molecule

Isomerase

Examples: racemase, mutase

Ligase

Catalyzes bond formation between two molecules AND requires energy (ATP, GTP, UTP)- H20 is often lost

Ligase

Examples: synthetase

Lyase

Catalyses the formation or breaking of a double bond AND is not a oxidoreductase, ligase, or hydrolase (Commonly associated with conversion between double and single bonds)

Lyase

Examples: pyruvate decarboxylase, fumarase

Translocase

Movement of a molecule, usually across a membrane

Oxidoreductase
