ABSTRACT:
The present invention relates to cellulases derived from the strain Myceliophthora thermophila and variants thereof comprising a core and optionally a C-terminal link consisting of 10 amino acids at the most, especially cellulases having a substrate binding cleft of a depth of at least 12 .ANG., exhibit enhanced enzyme activity in the alkaline pH range while exerting a moderate cellulolytic action on the cellulosic substrate and are, for example, useful in detergent compositions, especially for soil removal or color clarification or preventing backstaining; in fabric softeners; for bio-polishing of textiles; for drainage improvement of paper pulp; for deinking of old paper; for plant degradation.
