摘要:
The present invention provides isolated subtilisin variants. Specifically, a subtilisin variant is a mature form having proteolytic activity and comprises an amino acid sequence comprising the combination of amino acid substitutions: T022R/A, S101G, S103A, V104I, A232V, and Q245R, wherein the variant is a variant of Bacillus lentus subtilisin GG36 protease comprising the amino acid sequence shown in SEQ ID NO:2, and wherein the variant has at least 90% amino acid sequence identity to the amino acid sequence of SEQ ID NO: 2, and wherein the amino acid positions of the subtilisin variant are numbered according to the numbering of corresponding amino acid positions in the amino acid sequence of B. amyloliquefaciens subtilisin BPN' set forth as SEQ ID NO: 1. In addition, the present invention provides compositions comprising these subtilisin variants. In some embodiments, the present invention provides cleaning compositions comprising at least one of these subtilisin variants and methods of cleaning using the cleaning compositions.
摘要:
A method of treating and/or cleaning a surface, preferably a fabric surface comprising the steps of (i) contacting said surface with a composition in an aqueous wash liquor, said composition comprising an adjunct material and a protease variant wherein said protease variant is a variant of a parent protease said parent protease's sequence being at least 90% identical to the amino acid sequence of SEQ ID NO:1, wherein the amino acid positions of the protease variant are numbered according to the numbering of corresponding amino acid positions in the amino acid sequence of Bacillus amyloliquefaciens subtilisin BPN' shown in SEQ ID NO:2, wherein said protease variant comprises a mutation selected from T022A, T022R, T022Y, T022V, T022Q, T022L, T022W, and (ii) rinsing and/or drying the surface, wherein the temperature of the aqueous liquor is from 5 to 30°C.
摘要:
The present invention provides methods and compositions comprising at least one neutral metalloprotease enzyme that has improved storage stability. In some embodiments, the neutral metalloprotease finds use in cleaning and other applications. In some particularly preferred embodiments, the present invention provides methods and compositions comprising neutral metalloprotease(s) obtained from Bacillus sp. In some more particularly preferred embodiments, the neutral metalloprotease is obtained from B. amyloliquefaciens. In still further preferred embodiments, the neutral metalloprotease is a variant of the B. amyloliquefaciens neutral metalloprotease. In yet additional embodiments, the neutral metalloprotease is a homolog of the the B. amyloliquefaciens neutral metalloprotease. The present invention finds particular use in applications including, but not limited to cleaning, bleaching and disinfecting.
