Aminoacylation of tRNACys with cysteine. (a) Sequences of transcripts of etRNACys and htRNACys, showing the conserved U73 and GCA anticodon for aminoacylation and the non-conserved determinants at position 15–48 in the tertiary core and at base 37 in the anticodon loop. (b) Steady-state activity (kcat/Km) of aminoacylation of etRNACys and htRNACys by CysRS enzymes. (c) Single turnover activity (kchem/Kd) of aminoacylation of etRNACys and htRNACys by CysRS enzymes. Data are shown in a logarithmic scale and are the average of 3 determinations. Error bars represent standard deviations.
