title: [Small-angle scattering of the quaternary structure of phosphofructokinase from baker's yeast].
abstract: The phosphofructokinase (E.C. 2.7.1.11) from baker's yeast was examined by means of small angle X-ray scattering in 0.1 M K-phosphate buffer, pH 7. A quaternary structure model was obtained from the comparison of the model scattering curve with the experimental one. The eight subunits of the yeast phosphofructokinase are arranged in a D2-symmetry. The proposed scattering equivalent model corresponds to a structural description with a resolution of 2.5 nm. Models with a C8-symmetry and D4-symmetry can be ruled out.
