==Phospho-Aspartyl Intermediate Analogue of Phosphoserine phosphatase==
-
Protein phosphoaspartate bonds play a variety of roles. In response, regulator proteins of two-component signal transduction systems, phosphorylation of an aspartate residue is coupled to a change from an, inactive to an active conformation. In phosphatases and mutases of the, haloacid dehalogenase (HAD) superfamily, phosphoaspartate serves as an, intermediate in phosphotransfer reactions, and in P-type ATPases, also, members of the HAD family, it serves in the conversion of chemical energy, to ion gradients. In each case, lability of the phosphoaspartate linkage, has hampered a detailed study of the phosphorylated form. For response, regulators, this difficulty was recently overcome with a phosphate analog, BeF(3)(-), which yields persistent complexes with the active site, aspartate of their receiver domains. We now extend the application of this, analog to a HAD superfamily member by solving at 1.5-A resolution the, x-ray crystal structure of the complex of BeF(3)(-) with phosphoserine, phosphatase (PSP) from Methanococcus jannaschii. The structure is, comparable to that of a phosphoenzyme intermediate: BeF(3)(-) is bound to, Asp-11 with the tetrahedral geometry of a phosphoryl group, is coordinated, to Mg(2+), and is bound to residues surrounding the active site that are, conserved in the HAD superfamily. Comparison of the active sites of, BeF(3)(-) x PSP and BeF(3)(-) x CeY, a receiver domain/response regulator, reveals striking similarities that provide insights into the function not, only of PSP but also of P-type ATPases. Our results indicate that use of, BeF(3)(-) for structural studies of proteins that form phosphoaspartate, linkages will extend well beyond response regulators.
