CRYSTAL STRUCTURE OF THE CATALYTIC DOMAIN OF THE PROTEIN TYROSINE PHOSPHATASE SHP-1
Overview
The crystal structures of the protein-tyrosine phosphatase SHP-1 catalytic, domain and the complex it forms with the substrate analogue tungstate have, been determined and refined to crystallographic R values of 0.209 at 2.5 A, resolution and 0.207 at 2.8 A resolution, respectively. Despite low, sequence similarity, the catalytic domain of SHP-1 shows high similarity, in secondary and tertiary structures with other protein-tyrosine, phosphatases (PTPs). In contrast to the conformational changes observed in, the crystal structures of PTP1B and Yersinia PTP, the WPD loop, (Trp419-Pro428) in the catalytic domain of SHP-1 moves away from the, substrate binding pocket after binding the tungstate ion. Sequence, alignment and structural analysis suggest that the residues in the WPD, loop, ... [(full description)]
