MODES OF BINDING SUBSTRATES AND THEIR ANALOGUES TO THE ENZYME D-XYLOSE ISOMERASEMODES OF BINDING SUBSTRATES AND THEIR ANALOGUES TO THE ENZYME D-XYLOSE ISOMERASE
Structural highlights
Function[XYLA_STRRU] Involved in D-xylose catabolism. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedStudies of binding of substrates and inhibitors of the enzyme D-xylose isomerase show, from X-ray diffraction data at 1.6-1.9 A resolution, that there are a variety of binding modes. These vary in the manner in which the substrate or its analogue extend, on binding, across the carboxy end of the (betaalpha)(8)-barrel structure. These binding sites are His54 and the metal ion (magnesium or manganese) that is held in place by Glul81, Asp245, Glu217 and Asp287. Possible catalytic groups have been identified in proposed mechanisms and their role in the binding of ligands is illustrated. Modes of binding substrates and their analogues to the enzyme D-xylose isomerase.,Carrell HL, Hoier H, Glusker JP Acta Crystallogr D Biol Crystallogr. 1994 Mar 1;50(Pt 2):113-23. PMID:15299449[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
