Figure 2

Ca2+ sensitivity of Syt-7 (A and B) and Syt-1 (C) C2 domains. CaCl2 was titrated into solutions containing the indicated C2A (triangles), C2B (squares), or C2AB (circles) domains and liposomes. Data were normalized based on best fits to Eq. 1; the parameters from these fits are given in Table 2. Points and error bars shown are mean ± SD of three replicate titrations; where not visible, error bars are smaller than the symbol. Right panels show the extent of reversibility upon addition of 2.5 mM EDTA.
