Abstract
An endoprotease preparation, comprising an isolated endoprotease is disclosed. The endoprotease is a serine protease, shows immunochemical idenity to a protease derived from Fusarium oxysporum DSM 2672, hydrolyzes the oxidized beta-chain of bovine insulin at the peptide bonds Arg (22)-Gly (23) and Lys (29)-Ala(30), has optimum activity towards casein in the pH range of 8.5-11.0 with nearly constant activity in the pH range, has optimum activity at a temperature of about 45.degree. C., and has an isolectric point of about 9.0-10.0. The preferred microorganism that the enzyme is isolated from is Fusarium oxysporum DSM 2672.
