isozyme /iso·zyme/ (i´so-zīm) one of the multiple forms in which an enzyme may exist in an organism or in different species, the various forms differing chemically, physically, or immunologically, but catalyzing the same reaction.
isozyme.
isoenzyme [i″so-en´zīm]
i·so·zyme (  s -zm )n. Any of a group of enzymes that are similar in catalytic properties but are differentiated by variations in physical properties, such as isoelectric point. Also called isoenzyme. |

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.
