Soluble reductases with a temperature optimum of 80°C have been described from (a) Pseudomonas putida that reduces chromate to insoluble Cr(lll) (Park et al. 2000) and (b) Archaeoglobus fulgidus that can reduce Fe(IIl)-EDTA (Vadas et al. 1999). 

Isotope fractionation during sulfate reduction by the hyperthermophilic Archaeoglobus fulgidus varied with the concentration of sulfate, and it was suggested that different pathways were operative at concentrations >0.6 or <0.3 mM (Habicht et al. 2005).

Fig. 6. Multiple alignment of a putative zinc finger in pushover/calossin and two archaeal proteins. Conserved cysteines predicted to bind Zn2+ are shown as white-on-black. Annotation of this alignment is as Fig. 4. Species abbreviations as Figs. 4 and 5, except ARCFU, Archaeoglobus fulgidus METJA, Methanococcus jannaschii.
