Isozymes (also known as isoenzymes) are enzymes that differ in amino acid sequence but catalyze the same chemical reaction.
Isozymes, (or isoenzymes) are isoforms (closely related variants) of enzymes. In many cases, they are coded for by homologous genes that have diverged over time.

A different electrophoretic form of the same multi-subunit enzyme. Unlike allozymes isozymes are due to differing subunit configurations rather than allelic differences.

Isozymes Enzymes in an organism that catalyze the same reaction but differ in structure; these differences may range from one to several amino acid residues. Also called isoenzymes.
