Patent number: 7271139Abstract: 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).Type: GrantFiled: June 23, 2006Date of Patent: September 18, 2007Assignee: Novozymes A/SInventors: Noriko Tsutsumi, Jesper Vind, Shamkant Anant Patkar

Patent number: 7157263Abstract: 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.Type: GrantFiled: February 7, 2002Date of Patent: January 2, 2007Assignee: Novozymes A/SInventors: Signe Munk, Jesper Vind, Kim Borch, Shamkant Anant Patkar, Sanne O.

Patent number: 6939702Abstract: 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.Type: GrantFiled: March 30, 2000Date of Patent: September 6, 2005Assignee: Novozymes A/SInventors: Jesper Vind, Allan Svendsen, Shamkant Anant Patkar, Kim Vilbour Andersen, Dorte Aaby Halkier, Kirsten Bojsen
