A new model of substrate recognition for aminoacyl-tRNA ligases is described. It is possible to distinguish all amino acids in a binary code system of five binary digits, and all known E. coli and yeast tRNAs in a system of six to eight digits. The code agrees with experimental results published in
As a consequence of the existence of two classes of aminoacyl-tRNA synthetases (aaRSs), we de"ned two types of mutations: g (mutations that do not change the class of the involved amino acids) and u (those which change the class). We have found that the mean chemical distance resulting from g mutati
