Using 7.5% polyacrylamide gel electrophoresis, a heterogeneity of molecular forms of "malic" enzyme (EC 1.1.1.40) in corn leaves was established. Etyolated corn sprouts contain only one component of the enzyme, while in the green leaves 3 minor components were additionally found. A possible existence of the "malic" enzyme in two forms, a compact and a dissociating ones, is postulated. In comparison with the compact form the dissociating form of the enzyme is more active and possesses additional functional properties due to the presence of minor components.
