摘要:
An enzyme preparation comprising a modified enzyme selected from the group consisting of an amylase, lipase, oxidorcductase, pectinace or hemicellulase, the modified enzyme having an improved performance due to an alkaline pI and/or increased surface activity obtained by chemical modification or amino acid substitution, is useful e.g., in detergents, in baking flour, in animal feed, in the manufacture of cellulosic fabrics and for the treatment of lignocellulosic fibers.
摘要:
The present invention relates to a method of preparing a variant of a parent lipolytic enzyme, comprising (a) subjecting a DNA sequence encoding the parent lipolytic enzyme to random mutagenesis, (b) expressing the mutated DNA sequence obtained in step (a) in a host cell, and (c) screening for host cells expressing a mutated lipolytic enzyme which has a decreased dependance to calcium and/or an improved tolerance towards a detergent or a detergent component as compared to the parent lipolytic enzyme.

摘要:
The pharmaceutical use of lipases related to the Thermomyces lanuginosus (Humicola lanuginosa) lipase comprising amino acids 1-269 of SEQ ID NO: 2, optionally in combination with a protease and/or an amylase. Examples of medical indications are: Treatment of digestive disorders, pancreatic exocrine insufficiency (PEI), pancreatitis, cystic fibrosis, diabetes type I, and/or diabetes type II. The lipases of the invention have, e.g., an improved digestion performance in vitro, an improved activity at a pH in the neutral range, an improved stability at low pH, and are stable against protease-degradation, and/or are stable in the presence of pepsin and bile salts. The invention also relates to methods of determining digestion performance in vitro of lipases, as well as to certain novel variants of the lipase of T. lanuginosus.
