It is also evident that the TF.VIIa complex is proteolytically active and can activate the zymogen plasma factor X to the serine protease Xa in free solution, inferring that extended substrate recognition by induced structural loci of the TF.VIIa complex are created from either or both proteins to constitute a new recognition structure .
 protein: new recognition structure; protein: serine protease Xa; protein: TF.VIIa complex; protein: TF.VIIa complex; protein: zymogen plasma factor X
