Abstract: Endo-beta-1,4-xylanases hydrolyze arabinoxylan, a major constituent of cereal cell walls, and are nowadays widely used in biotechnological processes. Purified complexes of family 11 xylanases from Aspergillus niger and Bacillus subtilis with TAXI I, a TAXI-type xylanase inhibitor from Triticum aestivum L., were prepared. In both cases the complex was crystallized using the hanging-drop vapour-diffusion method. The needle-like crystals of TAXI I in complex with A. niger xylanase belong to the trigonal space group P3(1) or P3(2), with unit-cell parameters a = b = 88.43, c = 128.99 A, and diffract to 1.8 A resolution. TAXI I in complex with B. subtilis xylanase crystallizes in the monoclinic space group C2, with a = 107.89, b = 95.33, c = 66.31 A, beta = 122.24 degrees. Complete data sets were collected for both crystal types using synchrotron radiation.
