OXIDISED AZURIN II FROM ALCALIGENES XYLOSOXIDANS
Overview
Crystallographic structures of oxidized and reduced forms of azurin II are reported at 1.75 A resolution. Data were collected using one crystal in each case and by translating the crystal after each oscillation range to minimize photoreduction. Very small differences are observed at the Cu site upon reduction and these cannot be determined with confidence at current resolution. A comparison with the three-dimensional EXAFS reveals a good correspondence for all the ligand distances except for Cu-His46, where a larger deviation of approximately 0.12-0.18 A is observed, indicating that this ligand is more tightly restrained in the crystallographic refinement at the current resolution.
About this Structure
1DYZ is a Single protein structure of sequence from Achromobacter xylosoxidans with as ligand. This structure supersedes the now removed PDB entry 1ARN. Known structural/functional Site: . Full crystallographic information is available from OCA.
