Probing the interface between factor Xa and tissue factor in the quaternary complex tissue factor–factor VIIa–factor Xa–tissue factor pathway inhibitor

Abstract
Blood coagulation is triggered by the formation of a complex between factor VIIa (FVIIa) and its cofactor, tissue factor (TF). TF–FVIIa is inhibited by tissue factor pathway inhibitor (TFPI) in two s...
