How can the enzymes be classified? Explain giving examples.
Based on structure, enzymes can be classified into monomeric enzymes and oligomeric compounds.
- Monomeric enzymes: Enzymes which consist of only a single polypeptide chain, so they can't be dissociated into smaller units, for example, carboxypeptidase A, pepsin, chymosin etc.
- Oligomeric enzymes: Enzymes which consist of more than one polypeptide chain for example, lactate dehydrogenase, pyruvate dehydrogenase, tryptophan synthase.
