We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Bacillus pasteurii UreE (BpUreE) is a putative chaperone assisting the, insertion of Ni(2+) ions in the active site of urease. The x-ray structure, of the protein has been determined for two crystal forms, at 1.7 and 1.85, A resolution, using SIRAS phases derived from a Hg(2+)-derivative. BpUreE, is composed of distinct N- and C-terminal domains, connected by a short, flexible linker. The structure reveals the topology of an elongated, homodimer, formed by interaction of the two C-terminal domains through, hydrophobic interactions. A single Zn(2+) ion bound to four conserved, His-100 residues, one from each monomer, connects two dimers resulting in, a tetrameric BpUreE known to be formed in concentrated solutions. The, Zn(2+) ion can be replaced by Ni(2+) as shown by anomalous difference ... [[http://ispc.weizmann.ac.il/pmbin/getpm?11602602 (full description)]]

Bacillus pasteurii UreE (BpUreE) is a putative chaperone assisting the insertion of Ni(2+) ions in the active site of urease. The x-ray structure of the protein has been determined for two crystal forms, at 1.7 and 1.85 A resolution, using SIRAS phases derived from a Hg(2+)-derivative. BpUreE is composed of distinct N- and C-terminal domains, connected by a short flexible linker. The structure reveals the topology of an elongated homodimer, formed by interaction of the two C-terminal domains through hydrophobic interactions. A single Zn(2+) ion bound to four conserved His-100 residues, one from each monomer, connects two dimers resulting in a tetrameric BpUreE known to be formed in concentrated solutions. The Zn(2+) ion can be replaced by Ni(2+) as shown by anomalous difference maps obtained on a crystal of BpUreE soaked in a solution containing NiCl(2). A large hydrophobic patch surrounding the metal ion site is surface-exposed in the biologically relevant dimer. The BpUreE structure represents the first for this class of proteins and suggests a possible role for UreE in the urease nickel-center assembly.
