Error minimization level of 2-letter codes. Starting from a random permutation of amino acids assignments within the supercodons without question marks, optimization was performed to find the least costly assignment according (see Methods). (a) 9 amino acids, the optimum coincides with the code in Fig. 1, MP = 1; (b) additional assignment of Leu is included; the optimum differs from the code in Fig. 1 by permutations in the second column, MP = 0.986; (c) Leu and Ser are added, MP = 0.985; (d) only Ser is added, the optimum is the same code as in Fig. 1, MP = 1.
