Enzyme Classification and Isoenzymes Quiz

Inactive form of enzyme that becomes active after partial proteolysis

Genetically determined differences in primary structure, catalyze the same reaction but are formed from structurally different polypeptides, may have different subcellular and tissue distribution, may be combined from more subunits, may differ in kinetic properties, are usually determined by electrophoresis
