Isoaccepting species of histidine-specific transfer RNAs from baker's yeast

Histidyl-tRNAs and histidyl-tRNA synthetases in wild type and cytoplasmic petite mutants of Saccharomyces cerevisiae

“…Another interpretation, however, is that nDNA of respiratory competent yeast cells contains sequences not found in the nDNA of an isogenic p~s train. Takeishi et al (1972) andSingh et al (1973) have found four and six species, respectively, of tRNAHls in Saccharomyces cerevisiae. Some of the minor species are also charged preferentially by the E. coli synthetase.…”
