| Comment | The Xip gene previously identified as a chitinase gene belonging to glycosyl hydrolase family 10 and 11 (GH10 and GH11), is a homolog of wheat Xip1. The recent studies with direct enzymatic assays revealed that the gene Xip belongs to the glycosyl hydrolase family 18 (GH18) group. It inhibits the xylanases belonging to glycosyl hydrolase family 10 and 11 (GH10 and GH11). The protein encoded by the gene has endo-1,4-beta-D-xylanase inhibitor activity. It does not exhibit chitinolytic activity, even though its amino acid sequence exhibited highest similarity to sequences classified as class III chitinases. The wheat Xip1 is known to inhibit xylanases secreted preferably by fungal pathogens compared to those secreted by bacterial pathogens and may contribute to disease resistance processes.
