The structure of a GH10 xylanase from Fusarium oxysporum reveals the presence of an extended loop on top of the catalytic cleft

The structure of a xylanase from F. oxysporum (FoXyn10a) was determined at 1.94 Å resolution. FoXyn10a adopts the (β/α)₈-barrel fold of the GH10 family, with an extended loop above the catalytic site with potential implications for enzymatic function.
