Abstract
The invention relates to a novel high-alkaline protease, its use in the industrial or domestic fields and also compositions for said uses containing this protease. The protease of the invention is a selected triple mutant derived from certain precursor proteases from the subtilisin group, especially of the “subtilisin 309” type.
Claims12
An industrial process comprising cleaning a hard surface using a modified subtilisin protease wherein a substitution of arginine for the amino acids occurs at each of the amino acid positions homologous to positions 42, 114 and 115 of SEQ ID NO:
- 1.
A cleaning process comprising the application of a modified subtilisin protease to the manufacture of leather, wherein said modified subtilisin protease comprises a substitution of arginine for the amino acids occurring at each of the amino acid positions homologous to positions 42, 114 and 115 of SEQ ID NO:
- 1.
A composition for industrial applications comprising a modified subtilisin protease and at least one other ingredient conventionally used in formulations for cleaning hard surfaces, wherein said modified subtilisin protease comprises a substitution of arginine for the amino acids occurring at each of the amino acid positions homologous to positions 42, 114 and 115 of SEQ ID NO:
- 1.
A composition for use in the manufacture of leather comprising a modified subtilisin protease and at least one other ingredient conventionally used in formulations for manufacturing leather, wherein said modified subtilisin protease comprises a substitution of arginine for the amino acids occurring at each of the amino acid positions homologous to positions 42, 114 and 115 of SEQ ID NO:
