22 Dec 1993TL;DR: In this article, a method for stabilizing a lipase or an α-amylase towards the inactivation caused by peroxidase systems was proposed, in which variants a naturally occurring tyrosine residue has been deleted or substituted with a different amino acid residue at one or more positions.
Abstract: The present invention relates to lipase and α-amylase variants, stabilized towards the inactivation caused by peroxidase systems, in which variants a naturally occurring tyrosine residue has been deleted or substituted with a different amino acid residue at one or more positions. The invention also relates to a method of stabilizing a lipase or an α-amylase towards the inactivation caused by peroxidase systems, and detergent compositions comprising a lipase and/or an α-amylase variant of the invention.

06 Jul 1993TL;DR: In this article, the acid and aluminate are added in controlled amounts, optionally in the presence of a water miscible solvent, followed by separation of the supernatant from the precipitate.
Abstract: The method comprises simultaneous addition of acid and aluminate in controlled amounts, optionally in the presence of a water miscible solvent, followed by separation of the supernatant from the precipitate. Hereby impurities are more effectively separated from the enzyme which remains in the supernatant.

02 Jul 1993TL;DR: An enzyme with a relative activity of at least 70 % at a pH of about 9 and a temperature of about 50 °C is considered to be an oxidoreductase as discussed by the authors.
Abstract: Enzyme exhibiting cellobiose oxidase activity, which enzyme has a relative activity of at least 70 % at a pH of about 9 and a temperature of about 50 °C. An enzymatic agent comprising cellobiose oxidase and an endoglycanase and/or oxidoreductase. A process of bleaching paper pulp using cellobiose oxidase.

06 Jul 1993TL;DR: In the mutant α-amylase as discussed by the authors, one or more of the methionine amino acid residues is exchanged with any amino acid residue except for Cys and Met.
Abstract: In the mutant α-amylase one or more of the methionine amino acid residues is exchanged with any amino acid residue except for Cys and Met. The thus produced mutant α-amylase exhibits an improved stability in the presence of oxidizing agents and an improved thermoactivity at moderate low pH values. The mutant α-a amylase is well suited as an additive to detergents, dish washing agents and liquefaction agents.
