A novel endoglucanase derived from, a polynucleotide encoding the endoglucanase, and a cellulase preparation containing the endoglucanase are disclosed. The endoglucanase or cellulase preparation is available for a washing use or fabric processing, such as a color clarification of a cellulose-containing fabric, a reduction of fuzz, an improvement of the touch feel and appearance of the fabric, providing a localized color change to the fabric, or a reduction of stiffness.

Endoglucanase STCE and cellulase preparation containing the same

There is provided an endoglucanase enzyme, which is useful for reducing fuzz of regenerated cellulose-containing fabrics, improving the touch and appearance, color clarification, localized variation in color, reducing stiffness and using it as components of a detergent, as well as deinking waste paper and improving freeness of paper pulp. A cDNA coding for the endoglucanase enzyme NCE5 was cloned and its DNA sequence and amino acid sequence derived from it were determined.

Endoglucanase enzyme NCE5 and cellulase preparations containing the same

It is an object of the present invention to provide enzymes that have high endoglucanase activity and yet exhibit high activity even under alkaline conditions, and genes encoding the same. The enzyme according to the invention has the following properties: a) exhibiting endoglucanase activity; and b) capable of completely removing fuzz from regenerated cellulose fabrics at a concentration of 1 mg of the protein/L or below. The enzyme of the invention having endoglucanase activity is a protein comprising the amino acid sequence as shown in SEQ ID NO: 1, 3, 5, 7, 9 or 11; a modified protein thereof exhibiting endoglucanase activity; or a homologue of the protein or the modified protein.
