Table 3.
Suppression efficiency of tRNASer/Pyl chimeras
tRNA | Suppression efficiency, % |
---|---|
tRNACUASer | <5 |
Stabilized tRNACUASer | <5 |
tRNASer/Pyl chimera 1 | 62 |
tRNASer/Pyl chimera 2 | 69 |
tRNAPyl | 100 |
Suppression efficiency was measured by β-galactosidase activity in E. coli strain XAC/A24. In the absence of Cyc, background suppression in all cases was <5%.
