Abstract The nucleotide sequence at the 3′-end of 16Sr-RNA (nucleotides 1305–1508) was determined, by the primer extension method, for Mycobacterium smegmatis, Mycobacterium tuberculosis and Mycobacterium vaccae, in addition to Mycobacterium leprae. No differences in nucleotide sequence were detected, indicating that this region of 16SrRNA is highly conserved among mycobacteria. The nucleotide sequence common to the four above-mentioned mycobacteria differs from that reported for species of other genera. For example, for helix 39 (nucleotides 1408–1491) the mycobacterial sequence has 58% similarity with the Escherichia coli sequence, 74% similarity with the Bacillus subtilis sequence and 93% similarity with the Streptomyces sequence. The observations support the assignment of M. leprae to the genus Mycobacterium.
