Patent number: 9695461Abstract: The stabilization of a hydrolytic enzyme in a liquid preparation is to be improved through a component that stabilizes the hydrolytic enzyme. This is accomplished by a method for adapting a hydrolytic enzyme to a component that stabilizes the hydrolytic enzyme, comprising the following method steps: a) providing a hydrolytic enzyme (starting enzyme) and a component that stabilizes the hydrolytic enzyme and that comprises a reversible inhibitor of the hydrolytic enzyme; b) changing the amino acid sequence of the hydrolytic enzyme in at least one position, by substitution, deletion or insertion; c) determining the relative activity of the hydrolytic enzyme from step b) and the relative activity of the starting enzyme in a liquid preparation; d) selecting the hydrolytic enzyme that has a reduced relative activity by comparison with the relative activity of the starting enzyme.Type: GrantFiled: March 6, 2014Date of Patent: July 4, 2017Assignee: Henkel AG & Co. KGaAInventors: Petra Siegert, Stefan Evers, Marion Merkel, Nina Mussmann, Hendrik Hellmuth, Timothy O'Connell, Karl-Heinz Maurer, Ulrich Schwaneberg, Felix Jakob, Ronny Martinez, Brian Laufs, Ayhan Aydemir, Thomas Weber
