  • a The absolute number of occurrences of each codon was computed from 17 genes (see Table 3 for references):aspA, cpeY, cpeZ cpn60,dapA, dnaA, mpeX, pcb,ppeA, ppeB, psaA, psaB,psbA, ppeC, rnc, uvrD, andorf463. The noninformative Trp and Met codons are omitted. For uvrD, only the first 518 codons are known.
