  • Lipase variants
    Publication number: 20070161082
    Abstract: Attaching a peptide extension to the C-terminal amino acid of a lipase reduces the tendency to form odor. This may lead to lipase variants with a reduced odor generation when washing textile soiled with fat which includes relatively short-chain fatty acyl groups (e.g., up to C8) such as dairy stains containing butter fat or tropical oils such as coconut oil or palm kernel oil.

  • Phospholipase
    Publication number: 20070092945
    Abstract: The present invention is related to a method for producing a phospholipase by processing an expressed fungal peptide and to certain specified phospholipases. Furthermore the invention provides a method for producing cheese with a phospholipase.

    Publication date: April 26, 2007
    Applicants: Novozymes A/S, Chr. Hansen A/S
    Inventors: Mary Stringer, Tine Fatum, Shamkant Patkar
  • Phospholipase variants
    Publication number: 20060251763
    Abstract: The inventors have used protein engineering to develop variants of fungal phospholipases. Starting from a parent phospholipase, they have modified the amino acid sequence to arrive at variants which have phospholipase activity (generally, at roughly the same level as the parent enzyme) and have a lower lipase activity on triglycerides than the parent enzyme.

  • Chemically modified lipolytic enzyme
    Publication number: 20050281912
    Abstract: Lipolytic enzymes are chemically modified by covalently linking one or more (particularly 1-3) hydrophobic groups to the enzyme molecule. The chemical modification improves the performance of the lipolytic enzyme, e.g., in baking or in detergents.

  • Lipolytic enzyme variants
    Publication number: 20050059130
    Abstract: The substrate specificity of a lipolytic enzyme can be modified by making alterations to the amino acid sequence in a defined region of the lipolytic enzyme, so as to increase the level of a desired activity or to decrease the level of an undesired activity. Thus, the inventors have developed lipolytic enzyme variants with a modified amino acid sequence with a substrate specificity which can be tailored for specific uses.
