In weak protein complexes, however, the encounter state can represent a significant population of the complex. The redox proteins adrenodoxin (Adx) and cytochrome c (C c) associate to form such a weak and short-lived complex, which is nevertheless active in electron transfer. To study the conformational freedom within the protein complex, the native complex has been compared to a cross-linked counterpart by using solution scattering and NMR spectroscopy. Oligomerization behavior of the native complex in solution revealed by small-angle X-ray scattering indicates a stochastic nature of complex formation. For the cross-linked complex, interprotein paramagnetic effects are observed, whereas for the native complex, extensive averaging occurs, consistent with multiple orientations of the proteins within the complex. Simulations show that C c samples about half of the surface area of adrenodoxin. It is concluded that the complex of Adx/C c is entirely dynamic and can be considered as a pure encounter complex. #1: ジャーナル: J.Mol.Biol. / 年: 1990タイトル: High-resolution refinement of yeast iso-1-cytochrome C and comparisons with other eukaryotic cytochromes C 著者: Louie, G.V. / Brayer, G.D. #2: ジャーナル: Structure / 年: 1998タイトル: New aspects of electron transfer revealed by the crystal structure of a truncated bovine adrenodoxin, Adx(4-108) 著者: Muller, A. / Muller, J.J. / Muller, Y.A. / Uhlmann, H. / Bernhardt, R. / Heinemann, U. | ||||||
