  • Patent number: 7271139
    Abstract: The inventors have isolated novel lipolytic enzyme genes with a high homology to the T. lanuginosus lipase gene and thus well suited for use in gene shuffling. Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. The DNA shuffling technique is used to create a library of shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity. The invention also provides a polynucleotide comprising a nucleotide sequence encoding a lipolytic enzyme and a lipolytic enzyme (a polypeptide with lipolytic enzyme activity).

  • Patent number: 7157263
    Abstract: Attaching a peptide extension to the C-terminal amino acid of a lipase re-duces 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.

  • Patent number: 7091023
    Abstract: An esterase isolated from Aspergillus oryzae is capable of stereoselective hydrolysis of chiral esters and also has arylesterase activity (EC 3.1.1.2) and feruloyl esterase activity (EC 3.1.1.73). The esterase has only a limited homology to known amino acid sequences.

  • Patent number: 6964944
    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.

  • Patent number: 6939702
    Abstract: Certain variants of Lipolase (wild-type Humicolalanuginosa lipase) have a particularly good first-wash performance in a detergent solution. The variants should comprise one or more substitutions with positive amino acids near the N-terminal in the three-dimensional structure. The variants should further comprise a peptide addition at the C-terminal and/or should meet certain limitations on electrically charged amino acids at positions 90-101 and 210.
