[Study of properties of heat activated enzyme preparations].
The paper describes studies of heat treatment of the preparations amylorizin G10x, amylosubtilin G10x and glucoendomycopsin G15 and its effect on the relationshop between the rate of the enzymic reaction and the preparation concentration, optimal pH and temperatures, and the EDTA influence on the activity of heated preparations. After heating the preparations showed an elevation of optimal temperatures of their action and a shift of optimal pH to the alkaline region. Primary heating of the preparations resulted in an increase of the rate of the enzymic reaction. Heated preparations were less susceptible to the effect of the inhibitor that nonheated ones.
