摘要:
The present invention provides variants of a parent cellulase, such as, e.g., a cellulase classified in family 45 such as a Humicola insolens 43 kD endoglucanase, comprising a cellulose binding domain (CBD), a catalytically active domain (CAD), and a region linking the CBD and CAD (the linking region), wherein one or more amino acid residues of the CBD, CAD, or linking region is deleted or substituted by one or more amino acid residues and/or one or more amino acids are added to the linking region and/or another CBD is added at the opposite end of the CAD. Such variants have improved properties as regards, e.g., alkaline activity, compatibility with detergent composition ingredients, particular soil removal, color clarification, defuzzing, depilling, harshness reduction, and sensitivity to anionic surfactants. Such variants are useful, e.g., in detergent compositions, for textile treatment, in paper pulp processing, for animal feed, and for stone-washing of jeans.
摘要:
The present invention relates to an isolated enzyme exhibiting cellulolytic (endoglucanase) activity at alkaline pH, an enzyme composition comprising the enzyme, a DNA construct encoding the enzyme, methods for producing the enzyme or enzyme composition, a detergent composition comprising the enzyme, and methods for using the enzyme in, e.g., providing localized variation in the color density of dyed fabric, improving the drainage of an aqueous suspension of paper pulp, and de-inking of recycled paper.

摘要:
DNA sequences are disclosed encoding an enzyme exhibiting endoglucanase activity. The endoglucanase is useful in a variety of industrial processes requiring an alkaline cellulase.
摘要:
This invention relates to an enzyme which exhibits cellulase activity and is producible by a strain of Bacillus sp., NCIMB 40250, or a related Bacillus sp. strain, or a derivative of said cellulase. This invention also relates to an enzyme which comprises a core region derived from an endoglucanase combined with a cellulose-binding domain derived from another cellulase, or which comprises a core region derived from another cellulase combined with a cellulose-binding domain derived from an endoglucanase.
摘要:
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.
