Fig. 4. The effect of zinc ion on the activation of two bacterial adenylyl cyclase toxins, EF and CyaA, by CaM. Assays were performed at 30 °C for 10 min in the presence of 1 nM EF or CyaA with the indicated concentration of CaM either with 10 mM ZnCl[2] or 1 μM free calcium ion buffered by EGTA; data are a representative of two experiments.
