The hyperthermophilic Archaea represent some of the most ancient organisms on earth. A study of enzymatic cofactors in these organisms could provide basic information on the origins of related cofactors in man and other more recently evolved organisms. To this end, the nature of the tungsten cofactor in aldehyde ferredoxin oxidoreductases from Pyro...
In this communication the authors present new experiments and theoretical simulations, using iron L-edge X-ray absorption spectroscopy, to study the metalloprotein Pyrococcus furiosus rubredoxin. the 3d transition metal L-edges are found between 400 and 1100 eV, in the soft X-ray region. Synchrotron radiation beam lines producing the high photon fl...

... Molybdenum is a trace metal required by virtually every species, and tungsten can replace molybdenum in some instances (Kletzin & Adams, 1996). In most enzymes, both metals are found to be associated with an organic component called molybdopterin, often containing dinucleotides (Johnson et al., 1993). Early studies of tungsten-requiring enzymes in hyperthermophilic archaea have led to the discovery that tungsten has a biological role. ...
