Figure 5.

Distribution along the code wheel of GoU pairs. The triplets are organized from the center to the periphery so that the GC-rich codon:anticodon triplets are at the top (North) and the AU-rich codon:anticodon triplets at the bottom (South) of the wheel. Along the (red-line) diagonals are those triplets with intermediate energies (86). (A) The GoU pairs occurring in the AA-stem are shown next to the amino acid and those in red occur only in tRNAs specific for that amino acid. (B) The GoU pairs occurring in the D- (red), AC- (green) and T-stems (blue). Positions 15:48 (black) are G = C, except where indicated. When the specificity is attached to an isodecoder subfamily it is indicated in red.
