Abstract: | Cytochrome c3 from Desulfovibrio vulgaris Miyazaki F was successfully expressed in the facultative aerobe Shewanella oneidensis MR-1 under anaerobic, microaerophilic, and aerobic conditions, with yields of 0.3 to 0.5 mg of cytochrome/g of cells. A derivative of the broad-host-range plasmid pRK415 containing the cytochrome c3 gene from D. vulgaris Miyazaki F was used for transformation of S. oneidensis MR-1, resulting in the production of protein product that was indistinguishable from that produced by D. vulgaris Miyazaki F, except for the presence of one extra alanine residue at the N terminus. |
