TABLE 3.

Dimer dissociation constants in the absence and presence of cdG (in μm)

The molar cdG:protein ratio was 3:1 and divalent cation concentration 2 mm, where applicable.

Method Kd,00 = K00−1
Kd,11 = K11−1
−cdG, −M2+a −cdG, +Mg2+ −cdG, +Ca2+ +cdG, +Mg2+ +cdG, +Ca2+
MALS (Fig. 6C) 188 (80…1600) 36 (21…65) 13 (0.8…25) 1.1 (0.6…2.3)b 0.6 (0.3…1.1)b
AUC (Fig. 7) 0.4 (0.2…0.9)
Activity (Fig. 8C) 0.5 (0.47…0.54)

a Without divalent cations.

b Sample not fully complexed upon elution; ligand occupancy ∼0.7 as derived from combined UV/RI measurement. p = 0.95 confidence intervals are given in parentheses assuming a 5% error in the individual measurements.
