NUCLEOTIDE SEQUENCE OF THE 16S rRNA FROM AN ARCHAEA, HALOARCULA AIDINENS1S STRAIN B_2
艾丁嗜盐小盒菌B2菌株16S rRNA核苷酸序列

The sequence of the 16S rRNA from an Archaea, Haloarcula aidinensis strain B2 (Ha. B2) has been determined by PCR-based sequencing method. The sequence of the archaeal rRNA indicates typical archaeal features. Although Ha. B2 is closer in sequence to bacterial 16S rRNA than to the eucaryal 16S-like rRNA, its sequene shows certain specific similarities to eucaryal counterpart. In sequence and structure, the similarities of the Archaea (Ha. B2) with Bacteria or Eucarya are higher than the similarities between Bacteria and Eucarya. The comparison of this archaeal 16S rRNA sequence with those from other species of various halobacterial genera strongly supports the previous conclusion that the Ha. B2 should belong to a new species of Genus Haloarcula.
