Figure 4.
FIGURE 4. Calcium binding to Tcad1. For this
representation, the chemical shift changes in ^1H-^15N-HSQC of
Tcad1 with different concentrations of Ca^2+ (supplemental Fig.
S4) have been mapped onto a space-filling model of Tcad1 (middle
and right). Strong (red) and weak (orange) chemical shift
changes are observed only for residues in proximity to the
calcium binding sites (residues with green colored side chains
in the ribbon representation to the left, see also Fig. 1B).
Residues colored in yellow shift only very weakly.
