title: Survey on substrate specificity with regard to ATP analogs of aminoacyl-tRNA synthetases from E. coli and from Baker's yeast. Correlation to synthetase families.
abstract: The substrate specificity of twenty aminoacyl-tRNA synthetases from E. coli and thirteen enzymes from baker's yeast with regard to eight ATP analogs is investigated for a comparison of the active-site topography. The enzymes are arranged in a scheme of possible "enzyme families" and compared to earlier schemes.
