MONOHYDROGEN PHOSPHATE BINDING TO TRYPANOSOMAL TRIOSEPHOSPHATE ISOMERASEMONOHYDROGEN PHOSPHATE BINDING TO TRYPANOSOMAL TRIOSEPHOSPHATE ISOMERASE
Structural highlights
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 PubMedThe three-dimensional structure of triosephosphate isomerase complexed with the competitive inhibitor SO-4(2) was determined by X-ray crystallography to a resolution of 0.24 nm. A comparison with the native crystal structure, where SO-4(2) is bound, revealed five changes: (a) a 0.10-nm shift of the anion-binding site; (b) a further closing of the flexible loop of the enzyme; (c) a 'swinging in' of the side chain of the catalytic Glu, that is chi 1 changes from (+) to (-) synclinal; (d) an altered water structure; (e) a disappearance of the conformational heterogeneity at the C-terminus of strand beta 7. Some of these changes may be related to the different hydrogen-bond pattern about the two different anions. However, the distance of 0.10 nm between the sulphur and phosphorus positions is unexpected and remains intriguing. Anion binding at the active site of trypanosomal triosephosphate isomerase.
