Abstract

The present invention relates to polypeptides having xylanase activity and nucleic acid sequences encoding such polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid constructs as well as methods for producing and using the polypeptides. One specific application of the xylanase is the selective hydrolysis of pentose sugar components of hemicellulose-containing plant biomass. The nucleotide sequence may be used for the production of the xylanase or optimized mutants thereof.
