The X-ray crystal structure of the enzyme Streptomyces griseus aminopeptidase (SGAP) has been determined in its double zinc form to 1.75 A resolution, in its apo-enzyme from (zinc removed) to 2.1 A resolution, and as a mercury replaced derivative to 2.1 A resolution. The structure solution was achieved by single isomorphous replacement with phasing from anomalous scattering (SIRAS), followed by density modification with histogram matching. The protein consists of a central beta-sheet made up of… CONTINUE READING
