Abstract:
:A novel aa3-type cytochrome oxidase from the extremely halophilic archaeon, Halobacterium halobium, differs significantly from those of other prokaryotic and eukaryotic cytochrome oxidases (Fujiwara, T., Fukumori, Y., and Yamanaka, T. (1989) J. Biochem. 105, 287-292). In the present study, we cloned and sequenced the gene which encodes the cytochrome aa3 by using the polymerase chain reaction methods. The deduced amino acid sequence of subunit I of H. halobium cytochrome aa3 was more similar to that of subunit I of the eukaryotic cytochrome (44%, maize mitochondria) than that of the cytochrome from other bacteria (36%, Paracoccus denitrificans). The consensus sequence in putative metal binding residues is well-conserved also in H. halobium cytochrome aa3.
