TI  - The complex of Bacillus pasteurii urease with acetohydroxamate anion from X-ray
      data at 1.55 A resolution.
PG  - 110-8
AB  - The structure of Bacillus pasteurii urease inhibited with acetohydroxamic acid
      was solved and refined anisotropically using synchrotron X-ray cryogenic
      diffraction data (1.55 A resolution, 99.5% completeness, data redundancy = 26,
      R-factor = 15.1%, PDB code 4UBP). The two Ni ions in the active site are
      separated by a distance of 3.53 A. The structure clearly shows the binding mode
      of the inhibitor anion, symmetrically bridging the two Ni ions in the active site
      through the hydroxamate oxygen and chelating one Ni ion through the carbonyl
      oxygen. The flexible flap flanking the active site cavity is in the open
      conformation. The possible implications of the results on structure-based
      molecular design of new urease inhibitors are discussed.
