Binding sites for calcium
WebCaM binding Ca2+, and the domains of CaM binding the CTT are linked thermodynamic functions. To better understand regulation, we determined the energetics of CaM domains binding to peptides representing pre-IQ sites A1588, and C1614 and the IQ motif studied as overlapping peptides IQ1644 and IQ′1650 as well as their effect on calcium binding.
