Isozymes (also known as isoenzymes) are enzymes that differ in amino acid sequence but catalyze the same chemical reaction. The existence of isozymes permits the fine-tuning of metabolism to meet the particular needs of a given tissue or developmental stage (for example lactate dehydrogenase (LDH)). ...

What is the importance of isoenzyme?

Isoenzymes, or isozymes, are distinct, often readily separable forms of an enzyme elaborated by the same organism. Isozymes catalyze the same chemical reaction, but typically differ with respect to their primary structure, intracellular location, and physiological role.

What are the properties of isoenzymes?

Isoenzymes (also called isozymes) are alternative forms of the same enzyme activity that exist in different proportions in different tissues. Isoenzymes differ in amino acid composition and sequence and multimeric quaternary structure; mostly, but not always, they have similar (conserved) structures.
