Nucleotide sequence of initiator tRNA from Mycobacterium smegmatis

|May 11, 1984
Abstract:
The nucleotide sequence of initiator tRNA from Mycobacterium smegmatis was determined to be pCGCGGGGUGGAGCAGCUCGGDAGCUCGCUGGGCUCAUAACCCAGAGm7GUCG CAGGU psi 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 ribothymidine 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.
