Also known as isoenzymes, multiple forms of enzymes, izoenzymy, isoenzyme, isozymes

In biochemistry, isozymes (also known as isoenzymes or more generally as multiple forms of enzymes or isoforms) are enzymes that differ in amino acid sequence but catalyze the same chemical reaction. Isozymes usually have different kinetic parameters (e.g. different KM values), or are regulated differently. They permit the fine-tuning of metabolism to meet the particular needs of a given tissue or developmental stage.
