摘要: Abstract The sequences of Saccharomyces cerevisiae mitochondrial tRNA 1 Arg , 2 Gly Lys Leu and Pro are reported. Special structural features were found in which has A 8 C 21 48 instead the constant residues U pyrimidine 48, a excluded from basepairing bulging out TΨC stem. belong to two-codon families ending purine, have modified uridine wobble position, prevents misreading U. It is likely be 5-carboxymethylaminomethyluridine. an unmodified position allowing reading all four codons four-codon family. However, minor species belongs CGN family, position. This very unusual feature raises problem mechanism by CGA, CGG CGC recognized.
