Protein chemotaxonomy of genus Datura. IV. Amino acid sequence of Datura ferredoxins depends not on the species but the section of Datura plants from which it comes.
The complete amino acid sequences of [2Fe-2S] ferredoxins from Datura quercifolia (section Stramonium) and D. fastuosa (section Dutra) have been determined by automated Edman degradation of the entire Cm-protein and of the peptides obtained by tryptic digestion and CNBr treatment. The D. quercifolia and D. fastuosa ferredoxins exhibited identical amino acid sequences to D. stramonium (section Stramonium) and D. metal (section Dutra) ferredoxins, respectively. This result suggests that the amino acid sequence of Datura ferredoxins depends on the section but not the species of Datura plants.
