Table 2. Binding constants (KD) for pSu1(-1U), pATSerUG and pATSerUGGAAA.
Substrate | KD, μM | ΔΔG, kcal/mol |
---|---|---|
pSu1(-1U) | 0.0063±0.0026 | 1 |
pATSerUG | 1.2±0.067 | -3.2 |
pATSerUGGAAA | 0.93±0.18 | -3.1 |
KD values were determined at 10 mM Ca2+ and 25°C. Each KD value is an average of at least three independent experiments. ΔΔG values were calculated using the equation ΔΔG = -RTln [KD (pATSerUG or pATSerUGGAAA)/KD(pSu1(-1U)] [40].
