The present invention relates to an isolated polypeptide having xylanase activity, selected from the group consisting of:

Polypeptide having xylanase activity

The present invention provides hemicellulytic enzyme variants. Specifically, the present invention provides xylanase variants having one or more modifications as compared to a parent xylanase enzyme resulting in at least one improved property. In addition, the present invention provides compositions comprising a xylanase variant of the invention. The present invention also provides methods of degrading hemicellulotic material, including arabino-xylan using compositions comprising a xylanase variant of the invention.

Composition and methods comprising a xylanase enzyme variant

A GH10 xylanase variant is disclosed herein. This GH10 xylanase variant has increased thermostability compared with a parent GH10 xylanase enzyme comprising at least 90% sequence identity with the amino acid sequence of SEQ ID No. 1 wherein the variant has been modified at two or more of the following positions 7, 33, 79, 217 and 298 corresponding to the amino acid numbering of SEQ ID No. 1.
