comment:"\"Our SPR experiments reveal that, in absence of calcium, binding of LR4–5 to the BβC fragment is markedly reduced (Fig. 2 and Fig. 3, Table 1). At pH 5.5, with 0.25 mM EDTA, 60 μM of LR4–5 saturate 17.1% of the immobilized ligands after 60 s, 4 times less than the binding observed in presence of 1.5 mM CaCl2 under the same conditions (Fig. 2 and Fig. 3, Table 1). Similarly, under the same conditions, LR5 binding is slightly reduced without calcium, from 3.0% to 2.1% of Rmax (Fig. 2, Table 1), and LR4 binding is drastically reduced from 22.5% with calcium to 3.5% without the cation (Fig. 2, Table 1). Not surprisingly, depletion of calcium causes a greater effect on the binding of LR4 than on that of LR5, consistent with the larger conformational change reported for LR4 when it unfolds and releases Ca++ at pH 5.5 [41]. As it appears, both high calcium concentrations and low pH promote binding of LR domains to the β-propeller. At pH 7.0, with 0.25 mM EDTA, only residual binding to the β-propeller is observed for the LR4–5 pair, reaching 0.7% of Rmax after 60 s injection of LR4–5 (Fig. 2 and Fig. 3, Table 1), and we could not detect binding of the β-propeller to the isolated LR4 or LR5 modules (Fig. 2, Table 1).\""
