Dependence of enthalpy changes associated with Ca binding on temperature. a Rabbit TnC. a Mg-free TnC and b TnC in the presence of 1 mM Mg. Numbers attached indicate the particular site involved; 1 one of the Ca–Mg sites for which Ca binds first; 2 another Ca–Mg site for which Ca binds next; 3 and 4 Ca-specific sites. Yamada and Kometani [153]. b Bullfrog TnC. Symbols are the same as in a, except that the Mg concentration is 5 mM. Imaizumi and Tanokura [164]
