Abstract:
An isolated nucleic acid fragment comprising(a) a sequence encoding a polypeptide having carboxymethyl cellulase (CMCase), endoglucanase, and .beta.-glucanase activity and being indigenous to Aspergillus niger var. niger or Aspergillus niger var. tubigensis;(b) a sequence encoding a polypeptide having the amino acid sequence SEQ ID NO:2 or SEQ ID NO:4 or a variant thereof that differs by an addition, insertion or deletion of one or more amino acids, and which still has CMCase, endoglucanase and .beta.-glucanase activity; wherein said variant has an amino acid sequence that has at least 70% sequence identity to the polypeptides of SID. NO:2 or SID. NO:4; or(c) a sequence shown in SEQ ID NO:1 or 3, or sequence having at least 90% sequence identity to the sequence shown in SEQ ID NO:1 or 3 and encoding a peptide having CMCase, endoglucanase, and .beta.-glucanase activity.
