title: Conservation of hydrogenase and polyferredoxin structures in the hyperthermophilic archaebacterium Methanothermus fervidus.
abstract: A 3.3-kilobase-pair region of the Methanothermus fervidus genome encoding part of the small subunit and all of the large subunit of the methyl viologen-reducing hydrogenase and a polyferredoxin was cloned and sequenced. The sequence of this hyperthermophilic hydrogenase conforms to the consensus sequence established for procaryotic [NiFe] hydrogenases. Although the M. fervidus polyferredoxin is the same size as the Methanobacterium thermoautotrophicum ferredoxin, containing six tandemly arranged bacterial ferredoxinlike domains, these two proteins are predicted to be only 64% identical in their primary sequences.
