Multifunctional Enzymes

**Definition:** Molecules that contain multiple active sites which are used to catalyze more than one enzymatic reaction. Proteins in this class generally contain multiple active sites within a single peptide chain and may also contain more than one enzymatically active subunit. They are distinguished from MULTIENZYME COMPLEXES in that their subunits are not found as distinct enzymes.
