pbscie3 m4

Acts as a catalyst for biochemical processes

Enzymes undergo all the reactions of proteins
except denaturation.

Composed only of protein ( amino acid chains)

Has a nonprotein part in addition to a protein part

Cofactor is the protein part of the conjugated enzyme

Apoenzyme is the activator

The inactive form of apoenzyme

able to provide additional chemically reactive functional groups

biochemically active conjugated enzyme produced from an apoenzyme and a cofactor

Common coenzymes are vitamins and non-metal ions

Metal ion activators are organic and may be
bonded through coordinate covalent bonds

tightly incorporated into protein structure by covalent or noncovalent forces

Oxidoreductase is an enzyme that catalyzes an oxidation- reduction reaction. Hydrolase an enzyme that catalyzes the transfer of a functional group from one molecule to another
