• PubMed Abstract: 
  

  The 3D structure of the apo-pseudoazurin (copper free pseudoazurin) from Alcaligenes faecalis strain S-6 is determined and refined at pH 6.7 using X-ray diffraction data to 1.85 A resolution. The final crystallographic R-factor is 0.164. Comparing the structures of apo-pseudoazurin and the native (Cu2+) protein, we observed limited differences ranging between 0.1-0.4 A at the vicinity of the copper site, at the loops connecting the secondary structural elements, at certain beta-strands and at the amino and carboxy termini of the protein.
