UniProtKB accession:  Q8L5C6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Fungal xylanase inhibitor. Possesses competitive inhibiting activity against fungal endo-1,4-beta-D-xylanases belonging to glycoside hydrolase family 10 (GH10) and family 11 (GH11). Possesses also inhibitory activity towards barley alpha-amylases. Binding to xylanases or amylases is necessary for inhibition activity. May function in plant defense against secreted fungal pathogen xylanases. Is similar to class III chitinases, but does not exhibit chitinase activity.
