Analysis of genomic tRNA revealed presence of novel genomic features in cyanobacterial tRNA.

ABSTRACT: Transfer RNAs (tRNA) are important molecules that involved in protein translation machinery and acts as a bridge between the ribosome and codon of the mRNA. The study of tRNA is evolving considerably in the fields of bacteria, plants, and animals. However, detailed genomic study of the cyanobacterial tRNA is lacking. Therefore, we conducted a study of cyanobacterial tRNA from 61 species. Analysis revealed that; cyanobacteria contain thirty-six to seventy-eight tRNA gens per genome that encodes for 20 tRNA isotypes. The number of iso-acceptors (anti-codons) ranged from thirty-two to forty-three per genome. tRNAIle with anti-codon AAU, GAU, and UAU was reported to be absent from the genome of Gleocapsa PCC 73,106 and Xenococcus sp. PCC 7305. Instead, they were contained anti-codon CAU that i
