Three related strains of the genus Bacillus, viz. B. licheniformis, B. subtilis and Bacillus Q were all found to contain a minor species of 5 S RNA in an amount indicating that it is transcribed from only one of the multiple 5 S RNA cistrons known to be present in these strains. The major and minor types of 5 S RNA from each of the three strains could be separated from each other by polyacrylamide gel electrophoresis in the presence of urea. The complete nucleotide sequences of the minor B. subtilis and Bacillus Q 5 S RNAs have been determined. Comparison of these sequences to the previously determined sequence of the minor 5 S RNA from B. licheniformis (Raué et al., 1976) showed the three minor types of 5 S RNA to be identical except for the residues at positions 79, 85 and 95. Moreover, seven out of the eight sequence differences between the major and the minor 5 S RNA are the same in all three strains. Thus, the single cistron coding for minor 5 S RNA has been strongly conserved in all three strains, which may indicate a biological significance for the minor 5 S RNA species. © 1977 Springer-Verlag.
