This domain is found C-terminal in some aspartic proteinases and in xylanase inhibitors. The activity of these proteins is vital for plant-survival as xylanase produced by phytopathogens destroys plant cells. In TAXI-type inhibitors, this domain is important for the differences in xylanase specificity [1-3].	Domain
