## Abstract Xylanase (__endo__β1,4βΞ²βxylanase; EC 3.2.1.8) is an enzyme that catalyzes the hydrolysis reaction of xylan. The structure of the xylanase II (XYNII) molecule from __Trichoderma longibrachoatum__ (formerly __Trichoderma reesei__) in a solution and at different pH values has been studied
This paper describes the use of barium chloride to produce a heavy-atom derivative of xylanase II crystals from Trichoderma longibrachiatum, which was obtained either by cocrystallization or soaking. SAD phasing led to interpretable electron-density maps that allowed unambiguous chain tracing. In th
