abstract：:Sequence comparisons among methionyl-tRNA synthetases from different organisms reveal only one block of homology beyond the last beta strand of the mononucleotide fold. We have introduced a series of semi-conservative amino acid replacements in the conserved motif of yeast methionyl-tRNA synthetase. The results indica...
