The NMR structure of the oxidised wild-type cytochrome c3 from Desulfovibrio vulgaris Hildenborough was determined in solution. Using a newly developed methodology, NMR data from the K45Q mutant was then grafted onto data from the wild-type protein to determine the structure in the region of the mutation. The structural origins of the redox-Bohr effect and haem-haem cooperativities are discussed with respect to the redox-related conformational changes observed in solution.
