Binding of intrinsic ATPase inhibitor to mitochondrial ATPase--stoichiometry of binding of nucleotides, inhibitor, and enzyme.

abstract：:By monitoring the activation of protein C and the regulation of factor Xa-catalyzed thrombin formation by the activated protein C (APC) on the surface of human umbilical vein endothelial cells (HUVEC), we found that functional protein C was synthesized in cultured HUVEC and expressed thereon in the presence of vitamin...
