Milk clotting enzyme from the rain deer rennets

Abstract

The main technological characteristics of the enzyme from the rain deer rennets have been studied in comparison with calf and bovine pepsins. It was found that according to some properties such as correspodence to the Shtork and Zegelka law, correlation of the milk coagulating activity with Ca ions concentration as well as sensitivity to urea activity the enzyme is close to bovine pepsin rather than rennet one. Besides the enzyme from the rain deer rennets is the less heat stable one as compared to bovine pepsin and rennet. Distinctive feature of the rain deer milk coagulating enzyme is its low absolute and relative proteolitic activity that proves the enzyme to be highly specific
