X-ray crystal structure analysis of plastocyanin at 2.7 Å resolution

The three-dimensional structure of plastocyanin, a ‘blue’ or ‘Type 1’ copper-protein, has been determined at a resolution of 2.7 Å. The copper atom has a highly distorted tetrahedral coordination geometry. It is coordinated by a cysteine thiol group, a methionine thioether group, and two histidine i...

Description
Summary:The three-dimensional structure of plastocyanin, a ‘blue’ or ‘Type 1’ copper-protein, has been determined at a resolution of 2.7 Å. The copper atom has a highly distorted tetrahedral coordination geometry. It is coordinated by a cysteine thiol group, a methionine thioether group, and two histidine imidazole groups.
