CRYSTAL STRUCTURE OF SURE PROTEIN FROM T.MARITIMA IN COMPLEX WITH TUNGSTATE

Overview

Homologs of the Escherichia coli surE gene are present in many eubacteria, and archaea. Despite the evolutionary conservation, little information is, available on the structure and function of their gene products. We have, determined the crystal structure of the SurE protein from Thermotoga, maritima. The structure reveals the dimeric arrangement of the subunits, and an active site around a bound metal ion. We also demonstrate that the, SurE protein exhibits a divalent metal ion-dependent phosphatase activity, that is inhibited by vanadate or tungstate. In the vanadate- and, tungstate-complexed structures, the inhibitors bind adjacent to the, divalent metal ion. Our structural and functional analyses identify the, SurE proteins as a novel family of metal ion-dependent phosphatases.
