MOPII FROM CLOSTRIDIUM PASTEURIANUM (APO1)
Overview
MopII from Clostridium pasteurianum is a molbindin family member. These, proteins may serve as intracellular storage facilities for molybdate, which they bind with high specificity. High resolution structures of MopII, in a number of states, including the first structure of an apo-molbindin, together with calorimetric data, allow us to describe ligand binding and, provide support for the proposed storage function of the protein. MopII, assembles as a trimer of dimers and binds eight oxyanions at two types of, binding sites located at intersubunit interfaces. Two type 1 sites are on, the molecular 3-fold axis and three pairs of type 2 sites occur on the, molecular 2-fold axes. The hexamer is largely unaffected by the binding of, ligand. Molybdate is admitted to the otherwise inaccessible ... [(full description)]
