Plant wall degradative compounds and systems
The present invention relates to cell wall degradative systems, in particular to systems containing enzymes that bind to and/or depolymerize cellulose. These systems have a number of applications.
1. An isolated Saccharophagus degradans strain 2-40 polynucleotide encoding an amino acid sequence with xylanase activity and comprising a GH10 domain.
2. The polynucleotide of claim 1 , wherein the polynucleotide encodes a polypeptide comprising the amino acid sequence of Xyn10B.
3. An isolated Saccharophagus degradans strain 2-40 polypeptide with xylanase activity and comprising a GH10 domain.
4. The polypeptide of claim 3 , wherein the polypeptide comprises the amino acid sequence of Xyn10B.
5. A vector comprising an isolated Saccharophagus degradans strain 2-40 polynucleotide encoding an amino acid sequence with xylanase activity and comprising a GH10 domain.
6. The vector of claim 5 , wherein the polynucleotide encodes a polypeptide comprising the amino acid sequence of Xyn10B.
7. A host cell comprising an isolated Saccharophagus degradans strain 2-40 polynucleotide encoding an amino acid sequence with xylanase activity and comprising a GH10 domain.
8. The host cell of claim 7 , wherein the cell is an Escherichia coli cell.
9. The host cell of claim 7 , wherein the polynucleotide encodes a polypeptide comprising the amino acid sequence of Xyn10B.
