title: The amino acid sequence of ferredoxin II from Chlorobium limicola, a photosynthetic green bacterium.
abstract: The amino acid sequence of ferredoxin II from the photosynthetic green sulfur-reducing bacterium, Chlorobium limicola, was deduced to be: Ala-His-Arg-Ile-Thr-Glu-Glu-Cys-Thr-Tyr-Cys-Ala-Ala-Cys-Glu-Pro-Glu-Cys-Pro-Val-Asn-Ala-Ile-Ser-Ala-Gly-Asp-Glu-Ile-Tyr-Ile-Val-Asp-Glu-Ser-Val-Cys-Thr-Asp-Cys-Glu-Gly-Tyr-Tyr-Asp-Glu-Pro-Ala-Cys-Val-Ala-Val-Cys-Pro-Val-Asp-Cys-Ile-Ile-Lys-Val. The ferredoxin was shown to consist of 61 amino acids in a single polypeptide chain. The presence of 8 g-atoms of Fe and 8 mol of sulfide led to a calculated molecular weight of 7289. In constract to the ferredoxin I from C. limicola, ferredoxin II contains basic amino acids in positions 2 and 3 and 60 from the NH(2)-terminal end of the protein. The sequences of all the various ferredoxins from photosynthetic bacteria reported to date are compared with one another.
