tRNA Arg II of E. coli has 77 nucleotides. There are eight minor nucleotides including inosine and 2-methyladenosine. Except for a few differences, the structure of tRNA Arg II is very similar to the structure of tRNA Arg I reported by Murao et al.3. The major difference is in the size of dihydrouridine loop. tRNA Arg II does not contain 2-thiocytosine. The unidentified nucleoside X seems to be a different modification other than nucleoside N reported to be present in tRNA Arg I.
