isozyme[′ī·sə‚zīm] (biochemistry) isoenzyme isozyme
isoenzyme [i″so-en´zīm] any of several forms of an enzyme that all catalyze the same reaction but may differ in reaction rate, inhibition by various substances, electrophoretic mobility, or immunologic properties. Several enzymes, particularly alkaline phosphatase, lactate dehydrogenase, and creatine kinase, have clinically important isoenzymes. Isoenzymes are separated by electrophoresis, and the pattern indicates which damaged organ has released the enzymes.i·so·en·zyme (ī'sō-en'zīm), An enzyme (one of a group) that catalyze the same reaction but may be differentiated by variations in physical properties, such as isoelectric point, electrophoretic mobility, kinetic parameters, or modes of regulation, for example, lactate dehydrogenase, a tetramer composed of varying amounts of α and β subunits (that is, 4α, 3α + 1β, 2α + 2β, 1α + 3β, and 4β). Synonym(s): isozymeisozyme (ī′sə-zīm′)n. An isoenzyme. i′so·zy′mic adj.i·so·en·zyme (ī'sō-en'zīm) One of a group of enzymes that catalyze the same reaction but may be differentiated by variations in physical properties, such as isoelectric point, electrophoretic mobility, kinetic parameters, or modes of regulation. |
