A xylanase of M(r) 20,700 from the hyperproductive mutant D3 of the thermophillic Bacillus, strain XE has been purified and crystallized from 2-methyl-2,4-pentanediol. The unit cell is triclinic with a = 48.5 A, b = 51.5 A, c = 72.6 A, alpha = 90.4 degrees, beta = 95.4 degrees, gamma = 92.3 degrees (all +/- 0.2). There are four molecules in the asymmetric unit related by 222 symmetry. These crystals diffract to at least 2.5 A using X-rays from a rotating anode generator.
