“…Because Fe 2+ is coordinated with protoporphyrin IX in the fi nal step of heme biosynthesis, iron availability is critical for the performance of these respiratory enzymes especially in an aerobic environment. T. volcanium also possesses many respiratory enzymes and radical scavengers such as superoxide dismutase of T. acidophilum (Morris et al, 1985) carrying iron in their catalytic domains. And, as is the case with many Gram-negative bacteria, the genome of T. volcanium contains gene encoding Fur.…”

Because archaea possess many respiratory enzymes or radical scavengers with catalytic domains that contain iron, the expression of the genes encoding these enzymes might be regulated by iron acquisition. The genome of an archaeon, Thermoplasma volcanium contains a gene that encodes Fur (TVN0292). The fur gene of T. volcanium was amplifi ed by PCR, and cloned into plasmid pET28a. TvFur (T. volcanium Fur protein) was expressed in E. coli cells and then purifi ed. EMSA revealed that TvFur binds to its own promoter DNA. The binding to its own promoter was in an Mn 2+ -, Zn
