Isozymes
Another mechanism that our body uses to regulate enzyme activity involves using different forms of the same enzyme to catalyze a given biochemical reaction. These different forms of the same enzyme are known as isozymes or isoenzymes. Isozymes arise from different genes, have different sequences of amino acids and a different structure yet catalyze the same reaction, have different properties and exhibit different enzymes kinetics and are usually controlled by different allosteric effectors.
