  1. The Formal Oxidation-Reduction Potentials of Ferric-ferrous in Phosphoric Acid

    The formal redox potentials of the ferric-ferrous system have been determined in the media of perchloric (15), nitric (12), hydrochloric (13), sulfuric (15), and phosphoric (l) acids. The acids are named in the order of increasing extent to which the oxidation potential of the ferric-ferrous system …

  3. Ribonucleotide reduction and redox regulation in Archaea : surprising twists on a common theme

    To study the nucleotide reduction system in Archaea, we have expressed the Archaeoglobus fulgidus gene encoding the adenosylcobalamin (AdoCbl) dependent ribonucleotide reductase (afuRNR) protein. Initial characterization of the recombinant afuRNR indicates that it reduces CDP to dCDP in an AdoCbl …
