P.SHERMANII SOD(FE+3) FLUORIDE
Overview
The structure of the Propionibacterium freudenreichii subspecies shermanii, superoxide dismutase (SOD) was determined at various pH values. As a, comparison, the structure of the fluoride coordinated SOD was solved. The, SOD crystallizes at pH 6.1 in the space group C2221 with two subunits, A, and B, in the asymmetric unit. An increase of the pH value changes the, cell parameters slightly but not the symmetry of the crystals. The overall, structure of the SOD remains a compact tetrameter and is comparable to, that at pH 6.1 no matter whether the pH increases or fluoride is added. At, values above pH 7.4, an additional hydroxide ion can bind to the active, center. Its position is similar to the binding site of the fluoride. The, coordination number changes from five to six if the pH ... [(full description)]
