Characteristic features of tRNA^Arg and tRNA^Asp isoacceptors in various yeast species. tRNA genes were sought in eight yeast species (see Materials and Methods). Isoacceptors are named according to their anticodon triplets. In each case, the nucleotides at positions 37, 38 and 73 are given. Further, structural information on the nucleotide distribution in the subdomains α and β of the D-loops as well as the size of the variable regions (v) are indicated. Numbers indicate the percentage of identity of a given tRNA^Arg with tRNA^Asp in a same species. Along the left-hand side of the table, the pylogenetic link between the different yeast species is represented in a schematic diagram based on the rRNA sequences.
