Crystallization and preliminary X-ray diffraction studies of the catalytic core of acetyl xylan esterase from Trichoderma reesei

Acetyl xylan esterase is involved in the biodegradation of hemicellulose. It cleaves O-acetyl groups from xylan, which is the most abundant hemicellulose in nature. The catalytic core of acetyl xylan esterase from T. reesei has been crystallized and X-ray diffraction data at 2.3 Å collected. The crystal belongs to the triclinic space group P1 with unit-cell parameters a = 50.3, b = 62.1, c = 40.0 Å, α = 110.1, β = 113.6 and γ = 97.9°. The asymmetric unit contains two molecules.
