'''Crystal structure of O67745, a hypothetical protein from Aquifex aeolicus at 2.0 A resolution.'''<br />

==Overview==

Using single-wavelength anomalous dispersion data obtained from a, gold-derivatized crystal, the X-ray crystal structure of the protein, 067745_AQUAE from the prokaryotic organism Aquifex aeolicus has been, determined to a resolution of 2.0 A. Amino-acid residues 1-371 of the 44, kDa protein were identified by Pfam as an HD domain and a member of the, metal-dependent phosphohydrolase superfamily (accession No. PF01966)., Although three families from this large and diverse group of enzymatic, proteins are represented in the PDB, the structure of 067745_AQUAE reveals, a unique fold that is unlike the others and that is likely to represent a, new subfamily, further organizing the families and characterizing the, proteins. Data are presented that provide the first insights into the, structural organization of the proteins within this clan and a distal, alternative GDP-binding domain outside the metal-binding active site is, proposed.
