Structural Studies of Electron Transfer Proteins from Sulfate Reducing Bacteria: The Amino Acid Sequence of Two Rubredoxins Isolated from Desulfovibrio Vulgaris and Desulfovibrio Gigas
The sulfate reducing bacteria are still able to perform today a very ancient process: the dissimilatory reduction of sulfates. Ault and Kulp (1) have shown that a biological reduction of sulfates did occur on this planet as far back as 1 to 2.5 billion years, that is to say before the appearance of the atmospheric oxygen. Sulfate reducing bacteria were for a long time thought to contain a rather truncated electron transfer chain, but recent work in this field brought to light the fact that the 8 electron pairs necessary to reduce sulfate into hydrogen sulfide necessitate the presence of a rather sophisticated set of electron carriers.
