Crystal Structure of UreE from Helicobacter pylori (metal of unknown identity bound)Crystal Structure of UreE from Helicobacter pylori (metal of unknown identity bound)

Structural highlights

3la0 is a 4 chain structure with sequence from Atcc 43504. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Gene:HP_0070, ureE (ATCC 43504)
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[UREE_HELPY] Involved in urease metallocenter assembly. Binds nickel. Probably functions as a nickel donor during metallocenter assembly (By similarity).

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 PubMed

The crystal structure of the urease maturation protein UreE from Helicobacter pylori has been determined in its apo form at 2.1 A resolution, bound to Cu(2+) at 2.7 A resolution, and bound to Ni(2+) at 3.1 A resolution. Apo UreE forms dimers, while the metal-bound enzymes are arranged as tetramers that consist of a dimer of dimers associated around the metal ion through coordination by His102 residues from each subunit of the tetramer. Comparison of independent subunits from different crystal forms indicates changes in the relative arrangement of the N- and C-terminal domains in response to metal binding. The improved ability of engineered versions of UreE containing hexahistidine sequences at either the N-terminal or C-terminal end to provide Ni(2+) for the final metal sink (urease) is eliminated in the H102A version. Therefore, the ability of the improved Ni(2+)-binding versions to deliver more nickel is likely an effect of an increased local concentration of metal ions that can rapidly replenish transferred ions bound to His102.
