Isolation and characterization of a rubredoxin and an (8Fe-8S) ferredoxin from Desulfuromonas acetoxidans.
Biochim. Biophys. Acta 502, 38-44 (1978)
A two cluster (4Fe4S) ferredoxin and a rubredoxin have been isolated from the sulfur-reducing bacterium Desulfuromonas acetoxidans. Their amino acid compositions are reported and compared to those of other iron-sulfur proteins. The ferredoxin contains 8 cysteine residues, 8 atoms of iron and 8 atoms of labile sulfur per molecule; its minimum molecular weight is 6163. The protein exhibits an absorbance ratio of A385 A283 = 0.74. Storage results in a bleaching of the chromophore; the denatured ferredoxin is reconstitutable with iron and sulfide. The instability temperature is 52°C. The rubredoxin does not differ markedly from rubredoxins from other anaerobic bacteria.
