A, B	PF14543	Xylanase inhibitor N-terminal (TAXi_N)	Xylanase inhibitor N-terminal	This domain is found N-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 [1-3].	Domain
