title: The sequence of the 6S RNA gene of Pseudomonas aeruginosa.
abstract: From the gram-negative eubacterium Pseudomonas aeruginosa we have isolated a stable 6S RNA, approximately 180 nucleotides in length. The RNA was partially sequenced and identified by comparison with the known Escherichia coli 6S RNA sequence. Southern hybridizations revealed a single copy gene coding for the 6S RNA. DNA from other prokaryotes, i.e. E. coli, Thermus thermophilus, Bacillus subtilis, Bacillus stearothermophilus and Halobacterium maris mortui, did not give detectable hybridization signals. The 6S RNA gene was cloned in E. coli and its complete primary structure was determined. Although the 6S RNA sequences from P. aeruginosa and E. coli share only a 60.4% homology, we are able to propose a common secondary structural model.
