Abstract

The gene for ferredoxin from the hyperthermophilic archaeon Pyrococcus furiosus was cloned, sequenced, and expressed in Escherichia coli. The coding region confirmed the determined amino acid sequence. Putative archaeon-type transcriptional regulatory elements were identified. The fdxA gene appears to be an independent transcriptional unit. Recombinant ferredoxin was indistinguishable from the protein purified from P. furiosus in its thermal stability and in the potentiometric and spectroscopic properties of its [4Fe-4S] cluster.
