Studies in yeast showed that mtDNA transcribes tRNAs for 19 and probably for 20 amino acids, and for at least 2 isoaccepting tRNA species. The two met tRNA isoacceptors are shown to map at different sites and thus be transcribed from different mtDNA genes. Several other isoaccepting species noted on RPC-5 chromatography are still to be mapped. Evidence is presented for the presence of a mitochondrial tRNA/sup gln/, which is probably synthesized by transamidation of a missense glu tRNA/sup gln/intermediate, a pathway present in some bacteria but not in the cytoplasm of yeast or other eukaryotic cells. Several additional mt tRNA genes were mapped. (CH)
