Abstract
The present invention relates to variant EGIII cellulases that have improved stability and/or performance. The variant cellulases have replacements at sensitive residues to improve stability and/or performance.
Claims11
A variant T. reesei EGIII cellulase (SEQ ID NO:31) comprising a substitution at a residue which is sensitive to temperature, selected for the group consisting of W7, A35, H45, S63, S77, M79, H108, Y147, M154, T163, and/or N167 in EGIII.
A detergent composition comprising a surfactant and a variant EGIII cellulase consisting of a substitution at a position corresponding to one or more residues selected from the group consisting of W7, A35, H45, S63, S77, M79, H108, 147, M154, T163, and/or N167 in EGIII (SEQ ID NO:31).
