... investigated the effects of the mutation on the enzymatic maturation of FVIIa and on the response of FVIIa to TF.Our measurements, in both the presence and absenceof TF, revealed that the amidolytic ... effects of the G372(223)A mutation is slightlysubstrate-dependent. The fact that the relative reduc-tion in activity was not greater in the presence ofcofactor strongly suggests that the allosteric ... subsites located in the vicinity of the active site and sensed by the peptidyl substrate areinfluenced, in contrast to the remote exosites, e.g. in the vicinity of the activation pocket, that affect...
