Domain

Survival protein SurE-like phosphatase/nucleotidase (IPR002828)

Short name: SurE-like_Pase/nucleotidase

Domain relationships

None.

Description

This entry represents a SurE-like structural domain with a 3-layer alpha/bete/alpha topology that bears some topological similarity to the N-terminal domain of the glutaminase/asparaginase family. This domain is found in the stationary phase survival protein SurE, a metal ion-dependent phosphatase found in eubacteria, archaea and eukaryotes. In Escherichia coli, SurE also has activity as a nucleotidase and exopolyphosphatase, and may be involved in the stress response [PMID: 17561111]. E. coli cells with mutations in the surE gene survive poorly in stationary phase [PMID: 11709173]. The structure of SurE homologues have been determined from Thermotoga maritima [PMID: 11524683] and the archaea Pyrobaculum aerophilum [PMID: 12595266]. The T. maritima SurE homologue has phosphatase activity that is inhibited by vanadate or tungstate, both of which bind adjacent to the divalent metal ion.
