Preliminary XFEL data from spontaneously grown endo-1,4-β-xylanase crystals from Hypocrea virens.

ABSTRACT: The enzymatic degradation of semi-cellulosic substrates has recently received immense attention. The enzyme endo-1,4-β-xylanase is essential for the complete digestion of complex and heterogeneous hemicellulose. Here, the purification, crystallization and preliminary X-ray free-electron laser (XFEL) diffraction analysis of endo-1,4-β-xylanase from the fungus Hypocrea virens (HviGH11) are reported. Codon-optimized HviGH11 was overexpressed in Escherichia coli and spontaneously crystallized after His-tag purification and concentration. Preliminary XFEL diffraction data were collected at the Pohang Accelerator Laboratory XFEL (PAL-XFEL). A total of 1021 images containing Bragg peaks were obtained and indexed. The HviGH11 crystals belonged to the orthorhombic space group P2₁2_1<
