Evolution of the genetic code; Evidence from serine codon use disparity in Escherichia coli

Evolution of the genetic code; Evidence from serine codon use disparity in Escherichia coli

Among the 20 amino acids, three of them—leucine (Leu), arginine (Arg), and serine (Ser)—are encoded by six different codons. In comparison, all of the other 17 amino acids are encoded by either 4, 3, 2, or 1 codon. Peculiarly, Ser is separated into two disparate Ser codon boxes, differing by at least two-base substitutions, in contrast to Leu and Arg, of which codons are mutually exchangeable by a single-base substitution.
