Identical amino acid sequence of ferredoxin from Datura metel and D. innoxia
1Department of Pharmacognosy, Osaka University of Pharmaceutical Sciences, Japan.
Abstract:
The complete amino acid sequence of the respective [2Fe-2S] ferredoxins from Datura metel (D. alba) and D. innoxia, have been determined by automated Edman degradation of the entire Cm-protein and of the peptides obtained by tryptic digestion and CNBr treatment. The ferredoxins from the two plants had an identical amino acid sequence, suggesting a very close taxonomic relationship between the two. This is the first report for the identical primary structure of Fds from different species of higher plants.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
