High resolution crystallographic structure of the Clostridium thermocellum N-terminal endo-1,4-beta-D-xylanase 10B (Xyn10B) CBM22-1- GH10 modules complexed with xylohexaose

The structure was published by Najmudin, S., Pinheiro, B.A., Prates, J.A.M., Gilbert, H.J., Romao, M.J., and Fontes, C.M.G.A., in 2010 in a paper entitled "Putting an N-Terminal End to the Clostridium Thermocellum Xylanase Xyn10B Story: Crystal Structure of the Cbm22-1-Gh10 Modules Complexed with Xylohexaose." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2008.

The experimental data on which the structure is based was also deposited.
