Identity determinants of E. coli tRNAs.
Identity determinants of E. coli tRNA(Val) and three class II tRNAs, tRNA(Ser), tRNA(Tyr) and tRNA(Leu), are studied by using various variants of tRNA transcripts. Anticodon, discriminator base and acceptor stem are involved in the identity elements for tRNA(Val). Discrimination among class II tRNAs are considered to be dependent on the bases at positions 2, 71 and 73 as well as their different tertiary structures including the long variable arm.
