Nucleotide sequence of cytoplasmic initiator tRNA from Tetrahymena thermophila. 1981

Y Kuchino, and T Mita, and S Nishimura

The total primary structure of cytoplasmic initiator tRNA from Tetrahymena thermophila mating type IV, was determined by post labeling techniques. The sequence is pa-G-C-A-G-G-G-U-m1G-G-C-G-A-A-A-D-Gm-G-A-A-U-C-G-C-G-U-Psi-G-G-G-C-U-C-A-U-t6A -A-C-Psi-C-A-A-A-A-m7G-U-m5C-A-G-A-G-G-A-Psi-C-G-m1A-A-A-C-C-U-C-U-C-U-C-U-G-C- U-A-C-C-AOH. The nucleotide residue in the position next to the 5'-end of the anticodon of this tRNA (residue No. 33) is uridine instead of cytidine, which has been found in cytoplasmic initiator tRNAs from multicellular eukaryotic organisms. The sequence of three consecutive G-C base pairs in the anticodon stem common to all other cytoplasmic initiator tRNAs is disrupted in this tRNA; namely, the cytidine at residue 40 in this region is replaced by pseudouridine in Tetrahymena initiator tRNA.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012343	RNA, Transfer	The small RNA molecules, 73-80 nucleotides long, that function during translation (TRANSLATION, GENETIC) to align AMINO ACIDS at the RIBOSOMES in a sequence determined by the mRNA (RNA, MESSENGER). There are about 30 different transfer RNAs. Each recognizes a specific CODON set on the mRNA through its own ANTICODON and as aminoacyl tRNAs (RNA, TRANSFER, AMINO ACYL), each carries a specific amino acid to the ribosome to add to the elongating peptide chains.
