Table 2. Dissociation constants (Kd) for nucleotide binding to PDK3 with and without L2.
Kinase | Nucleotide | Kd (μM)a |
---|---|---|
PDK3 | ADP | 0.16±0.04 (n=3) |
PDK3-L2 | ADP | 1.30±0.14 (n=3) |
PDK3 | ATP | 0.16±0.005 (n=3) |
PDK3-L2 | ATP | 0.84±0.10 (n=3) |
PDK3 | ATPγS | 0.17 |
PDK3-L2 | ATPγS | 0.96 |
Dissociation constants for the binding of Mg-ADP, Mg-ATP, and Mg-ATPγS to MBP–PDK3 were measured by isothermal titration calorimetry in the absence and presence of lipoylated L2, as described in ‘Materials and methods'. | ||
aFor Mg-ADP and Mg-ATP in the absence or presence of L2, Kd values are expressed as mean±standard deviation. n=the number of experiments. |
