Patent
The present invention provides a novel cellulase nucleic acid sequence, designated BagCel, and the corresponding BagCel amino acid sequence. The invention also provides expression vectors and host cells comprising a nucleic acid sequence encoding BagCel, recombinant BagCel proteins and methods for producing the same.
1. A substantially purified polypeptide comprising the amino acid sequence of SEQ ID NO: 3 and having cellulase activity.
2. A purified polypeptide having cellulase activity prepared by
(a) culturing a host cell transformed with an expression vector in a suitable culture medium under suitable conditions to produce the cellulase; and
(b) obtaining said produced cellulase,
wherein the expression vector comprises a polynucleotide that encodes a polypeptide comprising the amino acid sequence of SEQ ID NO:3 and is operably linked to one or more control sequences that direct the production of the polypeptide in the host cell.
3. A detergent composition comprising the substantially purified polypeptide of claim 1 .
4. The detergent composition according to claim 3 further comprising a surfactant.
5. The detergent composition according to claim 3 , wherein said detergent is a laundry detergent.
6. The detergent composition according to claim 3 , wherein said detergent is a dish detergent.
7. A feed additive comprising the substantially purified polypeptide according to claim 1 .
