Publication number: 20080274938Abstract: Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Protease variants are provided that contain substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more negative or less positive compared to a precursor protease and thus the protease variant is more effective in a low detergent concentration system than a precursor protease.Type: ApplicationFiled: October 27, 2006Publication date: November 6, 2008Inventors: Ayrookaran J. Poulose, Volker Schellenberger, James T. Kellis, Paech Christian, Joanne Nadherny, Donald P. Naki, Katherine D. Collier, Robert M. Caldwell

Patent number: 6927055Abstract: Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue correspond to positions 62, 212, 230, 232, 252 and 257 of Bacillus amyloliquefaciens subtilisin.Type: GrantFiled: August 27, 2002Date of Patent: August 9, 2005Assignee: Genencor International, Inc.Inventors: Ayrookaran J.

Publication number: 20020155460Abstract: Methods of creating libraries of biological polymers are provided. The construction of a library employs a probability matrix for a reference sequence, and a constraint vector for which is applied to the probability matrix to produce a substitution scheme. The substitution scheme is then used to generate a library comprising substitutions recommended by the substitution scheme. The library members, or host cells comprising and/or expressing them, can be screened for desired changes in a property of interest in the biological polymers in the library.Type: ApplicationFiled: October 10, 2001Publication date: October 24, 2002Applicant: Genencor International Inc.Inventors: Volker Schellenberger, Donald P.

Publication number: 20020072064Abstract: An approach for detecting polymers and polymer fragments by analyzing mass analysis data of mixtures that include labeled versions of the polymers is disclosed. A library of polymer fragments is generated based on the possible fragments of a parent polymer. For each fragment in the library, a theoretical mass for both a natural version and a labeled version is generated. The labeled version may be based on a heavier isotope of an element. Data from a mass analysis, such as a mass spectrographic analysis, is received and automatically analyzed to identify whether a mass doublet is observed for each fragment in the library. The mass doublets correspond to the mass peaks of the natural and labeled versions of the fragments in the library. A determination is made whether a particular mass peak is from a labeled parent polymer or whether the particular mass peak is from an unlabeled source.Type: ApplicationFiled: August 17, 2001Publication date: June 13, 2002Inventors: Donald P. Naki, Ayrookaran J. Poulose
