Abstract
The present invention relates to novel subtilase variants exhibiting increased stability and preferably on par or improved wash performance. The variants of the invention are suitable for use in e.g. cleaning or detergent compositions, such as laundry detergent compositions and dish wash compositions, including automatic dish wash compositions. The present invention also relates to isolated DNA sequences encoding the variants, expression vectors, host cells, and methods for producing and using the variants of the invention.
Claims12
A subtilase variant of a subtilase parent having protease activity and having at least 25% improved stability compared to a subtilase with SEQ ID NO:
- 1, when measured as described in the accelerated storage stability assay in Example 3 herein, wherein the variant subtilase is a polypeptide that has at least 60%, e.g., at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98% but less than 100% sequence identity to the polypeptide of SEQ ID NO:
- 1.
