The invention further relates to mutant genes encoding such variants and cleaning and personal care compositions comprising such variants.Type: GrantFiled: July 18, 2000Date of Patent: July 1, 2003Assignee: The Procter & Gamble CompanyInventors: Elizabeth Ellen Sikorski, Donn Nelton Rubingh

Patent number: 6586224Abstract: The present invention relates to variants of subtilisin-like proteases having decreased immunogenicity relative to their corresponding wild-type proteases. The present invention further relates to such variants additionally having one or more amino acid substitutions in one or more epitope regions or additionally having one or more stabilizing substitutions. The invention further relates to mutant genes encoding such variants and cleaning and personal care compositions comprising such variants.Type: GrantFiled: July 18, 2000Date of Patent: July 1, 2003Assignee: The Procter & Gamble CompanyInventors: Donn Nelton Rubingh, Elizabeth Ellen Sikorski

Patent number: 6586221Abstract: Novel carbonyl hydrolase variants derived from the DNA sequences of naturally-occurring or recombinant non-human carbonyl hydrolases are disclosed. The variant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor carbonyl hydrolase. Such variant carbonyl hydrolases have properties which are different from those of the precursor hydrolase, such as altered proteolytic activity, altered stability, etc.Type: GrantFiled: October 13, 1994Date of Patent: July 1, 2003Assignee: Genencor International, Inc.Inventors: Thomas P. Graycar, Richard R. Bott, Lori J. Wilson

Patent number: 6569830Abstract: Co-administration of a lysostaphin or other anti-staphylococcal agent which cleaves cross-links of peptidoglycans of staphylococci cell walls such as lysostaphin and an antibiotic effective against staphylococci due to antibiotic activity mediated by cell-wall activity is effective against staphylococcal infection, even staphylococci that may be resistant to one or other of lysostaphin or the cell-wall active antibiotic. Co-administration simultaneously suppresses the generation of antibiotic-resistant mutant strains. Effective cell-wall active antibiotics include &bgr;-lactams and glycopeptides.Type: GrantFiled: March 5, 1999Date of Patent: May 27, 2003Assignee: Ambi, Inc.Inventors: Michael Climo, Ellen Murphy, Gordon Archer

Patent number: 6545006Abstract: The invention relates to a process for obtaining L-dihydroorotic acid by chromatography on an anionic exchange material in a base water mixture under a pressure from about 1.1 MPa to about 40 MPa. The process can be used to investigate the in vitro and in vivo activity of N-(4-trifluoromethylphenyl)-5-methylisoxazole-4-carboxamide, N-(4-trifluoromethylphenyl)-2-cyano-3-hydroxycrontonamide and similar compounds.Type: GrantFiled: December 11, 2000Date of Patent: April 8, 2003Assignee: Aventis Pharma Deutschland GmbHInventors: Ulrike Milbert, Robert Bartlett, Eric Ruuth, Claude Fudali
