Abstract
There are at least nine, and probably ten, ribosomal RNA gene sets in the genome of Bacillus subtilis. Each gene set contains sequences complementary to 16S, 23S and 5S rRNAs. We have determined the nucleotide sequences of two DNA fragments which each contain 165 base pairs of the 16S rRNA gene, 191 base pairs of the 23S rRNA gene, and the spacer region between them. The smaller space region is 164 base pairs in length and the larger one includes an additional 180 base pairs. The extra nucleotides could be transcribed in tRNAIIe and tRNA Ala sequences. Evidence is also presented for the existence of a second spacer region which also contains tRNAIIe and tRNA Ala sequences. No other tRNAs appear to be encoded in the spacer regions between the 16S and 23S rRNA genes. Whereas the nucleotide sequences corresponding to the 16S rRNA, 23S rRNA and the spacer tRNAs are very similar to those of E. coli, the sequences between these structural genes are very different.Entities:
