ABSTRACT:
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.
