    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, an 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.

    摘要: The present invention relates to a method for producing phytase variants has at least 70% identity to a phytase derived from Buttiauxella and comprises at least one additional disulfide bond as compared to this phytase. These phytase variants have modified, preferably improved, properties, such as thermostability, temperature profile, pH profile, specific activity, performance in animal feed, reduced protease sensitiliby, and/or an modified glycosylation pattern. The invention also relates to the variants produced, DNA encoding these phytases, methods of their production, as well as the use thereof, e.g. in animal feed and animal feed additives.
