==Crystal structure of S. typhimurium AphA complexed with cyclic-AMP==
-
The aphA gene of Salmonella enterica sv. Typhimurium strain MD6001 was cloned in the multicopy plasmid pBluescript SK(-). The recombinant AphA protein was purified to homogeneity. The protein crystallized in the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 112.4, b = 130.2, c = 139.6 A. Consistent with the self-rotation function, there are two tetramers in the asymmetric unit, indicating a solvent content of approximately 54%. The crystals are composed of biologically active AphA molecules.
