title: Crystallization and preliminary X-ray diffraction study of a xylanase from Trichoderma harzianum.
abstract: A 20,000 Mr xylanase from Trichoderma harzianum has been purified and crystallized from 20% (w/v) saturated ammonium sulphate solutions. The unit cell is orthorhombic, space group P2(1)2(1)2(1), with unit cell lengths a = 44.2 A, b = 94.1 A, c = 51.6 A. Data from native crystals and several potential heavy-atom derivatives have been collected. An X-ray analysis to at least 2.8 A resolution appears to be feasible.
