Abstract

See full text

The present invention relates to xylanase variants, comprising an alteration at least at one position corresponding to position 87 of the polypeptide of SEQ ID NO: 3, wherein the variant has xylanase activity and has increased xylanase inhibitor tolerance compared to the xylanase of SEQ ID NO: 3; and i) wherein the variant has at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99%, but less than 100% sequence identity to the polypeptide of SEQ ID NO: 3; or ii) wherein the number of alterations is 1-20, e.g., 1-10 such as 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 alterations. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
