... In this context it should be noted that mutation of Ca 2+ ligating amino acids in the N-terminal part of the first EGF-like domain of factor X influences the amidolytic activity of the intact protein ... Early studies employing equilibrium dialysis established the existence of about 10 Ca 2+ -binding sites, at least three of which mediate cooper- ative binding [23–26]. By studie...
