Isoenzymes are a class of related enzymes that catalyze identical biochemical reactions but possess distinct physicochemical properties due to differences in their polypeptide chain composition and quaternary structure. These variants, which exist exclusively as polymeric forms such as tetramers or dimers, display different kinetic parameters and electrophoretic mobilities, allowing for tissue-specific localization. This theoretical framework enables the differentiation of enzymatic activity within complex biological systems without altering the fundamental reaction mechanism they facilitate.
