Summary

The nucleotide sequence of an entire spacer region between the 16S and 23S rRNA genes of the rrnA operon from a blue-green alga, Anacystis nidulans, has been determined. The spacer region is 545 base pairs long and encodes tRNAfle and tRNAAla in the order of 16S rRNA-tRNAfle-tRNAAla-23S rRNA. A striking feature is that the A. nidulans tRNAfle gene contains no 3′-CCA sequence while the tRNAAla gene does. These spacer tRNA genes show strong sequence homology with those of chloroplasts and bacteria.
