Nucleotide sequence of the mitochondrial genes coding for tRNAglyGGR and tRNAvalGUR.
Yeast mitochondrial DNA-pBR322 recombinant DNA molecules known to contain tRNA genes from a tRNA rich region of the yeast genome were used as a source of DNA for restriction mapping and tRNA gene sequence analysis. We report here restriction maps of two segments of yeast mitochondrial DNA and the sequence of mitochondrial genes coding for tRNAglyGGR and tRNAvalGUR. Both genes are flanked by A + T rich DNA and neither has an intervening sequence nor codes for a 3' CCA end. The tRNA structures deduced from the genes have the usual cloverleaf structures and invariant nucleotides. This combination of DNA sequencing and restriction mapping has enabled us to determine that the tRNAvalGUR and a previously sequenced tRNA, the tRNApheUUY are transcribed from the same strand of DNA.
