The nucleotide sequence of initiator tRNA from Mycobacterium smegmatis was determined to be pCGCGGGGUGGAGCAGCUCGGDAGCUCGCUGGGCUCAUAACCCAGAGm7GUCGCAGGU
CGm1AAUCCUGUCCCCGCUACCAOH. The nucleotide sequence of Mycobacterium initiator tRNA was found to be the same as that of Streptomyces initiator tRNA, except that G46 and A57 were replaced by m7G46 and G57, respectively. The striking feature of Mycobacterium initiator tRNA is the absence of ribothymldine at residue 54, and the presence of 1-methyladenosine at residue 58 which makes the sequence of this tRNA similar to that of eukaryotic initiator tRNA.
