| 520 | 3 | |a The effects of iron limitation on the electron transport chain of the extremely halophilic Euryarchaeon Halobacterium salinarum were analyzed. When iron was growth-limiting, the respiratory rates as well as the inhibition pattern of the membranes were significantly different from membranes of iron replete cells. Changes in the availability of iron cause the formation of different respiratory pathways including different entry sites for electrons, different terminal oxidases of the respiratory chain, and drastic changes of the cytochrome composition and of the relative amounts of cytochromes. Under iron-limiting conditions, mainly low-potential cytochromes were measured. EPR spectroscopic studies revealed that the amount of proteins containing iron-sulfur clusters is reduced in membranes under iron-limiting growth conditions. Taken together, our results strongly suggest for the first time an important role of iron supply for the bioenergetics of an Archaeon. | |
