OXIDIZED STRUCTURE OF CYTOCHROME C3 FROM DESULFOVIBRIO DESULFURICANS ATCC 27774 AT PH 7.6
Overview
The tetraheme cytochrome c3 is a small metalloprotein with ca. 13,000 Da, found in sulfate-reducing bacteria, which is believed to act as a partner, of hydrogenase. The three-dimensional structure of the oxidized and, reduced forms of cytochrome c3 from Desulfovibrio desulfuricans ATCC 27774, at pH 7.6 were determined using high-resolution X-ray crystallography and, were compared with the previously determined oxidized form at pH 4.0., Theoretical calculations were performed with both structures, using, continuum electrostatic calculations and Monte Carlo sampling of, protonation and redox states, in order to understand the molecular basis, of the redox-Bohr and cooperativity effects related to the coupled, transfer of electrons and protons. We were able to identify groups that, showed ... [(full description)]
