Ultra high-resolution X-ray crystallographic studies of CBMs have helped to decipher the basis for specificity in carbohydrate-protein interactions. However, additional studies are needed to better understand which structural determinants confer which carbohydrate-binding properties. To address these issues, neutron crystallographic studies were initiated on one experimentally engineered CBM derived from a xylanase, X-2 L110F, a protein that is able to bind several different plant carbohydrates such as xylan, [beta]-glucan and xyloglucan. This protein evolved from a CBM present in xylanase Xyn10A of Rhodothermus marinus. The protein was complexed with a branched xyloglucan heptasaccharide. Large single crystals of hydrogenous protein (~1.6 mm3) were grown at room temperature and subjected to H/D exchange. Both neutron and X-ray diffraction data sets were collected to 1.6 Å resolution. Joint neutron and X-ray refinement using phenix.refine showed significant density for residues involved in carbohydrate binding and revealed the details of a hydrogen-bonded water network around the binding site. This is the first report of a neutron structure of a CBM and will add to the understanding of protein-carbohydrate binding interactions. 000276224 536__ $$0G:(DE-HGF)POF3-6G15$$a6G15 - FRM II / MLZ (POF3-6G15)$$cPOF3-6G15$$fPOF III$$x0 000276224 536__ $$0G:(DE-HGF)POF3-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)$$cPOF3-623$$fPOF III$$x1 000276224 588__ $$aDataset connected to CrossRef 000276224 65027 $$0V:(DE-MLZ)SciArea-160$$2V:(DE-HGF)$$aBiology$$x0 000276224 65027 $$0V:(DE-MLZ)SciArea-240$$2V:(DE-HGF)$$aCrystallography$$x1 000276224 65017 $$0V:(DE-MLZ)GC-130-2016$$2V:(DE-HGF)$$aHealth and Life$$x1 000276224 65017 $$0V:(DE-MLZ)GC-130-1$$2V:(DE-HGF)$$aHealth and Life$$x0 000276224 693__ $$0EXP:(DE-MLZ)BIODIFF-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)BIODIFF-20140101$$6EXP:(DE-MLZ)NL1-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eBIODIFF: Diffractometer for large unit cells$$fNL1$$x0 000276224 7001_ $$0P:(DE-HGF)0$$avon Schantz, Laura$$b1 000276224 7001_ $$0P:(DE-Juel1)138266$$aSchrader, Tobias E.$$b2$$ufzj 000276224 7001_ $$0P:(DE-HGF)0$$aOstermann, Andreas$$b3 000276224 7001_ $$0P:(DE-HGF)0$$aLogan, Derek T.$$b4 000276224 7001_ $$0P:(DE-HGF)0$$aFisher, S.
