Abstract

A study to compare the kinetics of activation of factor IX by Factor XIa/Ca2+ and by Factor VIIa/tissue factor/Ca2+ has been undertaken. When purified human proteins, detergent-extracted brain tissue factor and tritiated-activation-peptide-release assays were utilized, the kinetic constants obtained were: Km = 310 nM, kcat. = 25 min-1 for Factor XIa and Km = 210 nM, kcat. = 15 min-1 for Factor VIIa. The kinetic constants for the activation of Factor X by Factor VIIa/brain tissue factor were: Km = 205 nM, kcat. = 70 min-1. Predicted rates for the generation of Factor IXa and Factor Xa were obtained when human monocytic tumour U937 cells (source of tissue factor) and Factor VIIa were used to form the activator. In other experiments, inclusion of high-Mr kininogen did not increase the activation rates of Factor IX by Factor XIa in the presence or absence of platelets and/or denuded rabbit aorta. These kinetic data strongly indicate that both Factor XIa and Factor VIIa play physiologically significant roles in the activation of Factor IX.

摘要

已开展一项研究,以比较因子XIa/Ca2+和因子VIIa/组织因子/Ca2+对因子IX的激活动力学。当使用纯化的人蛋白、经去污剂提取的脑组织因子和氚标记的激活肽释放测定法时,获得的动力学常数为:因子XIa的Km = 310 nM,kcat. = 25分钟-1;因子VIIa的Km = 210 nM,kcat. = 15分钟-1。因子VIIa/脑组织因子对因子X的激活动力学常数为:Km = 205 nM,kcat. = 70分钟-1。当使用人单核细胞肿瘤U937细胞(组织因子来源)和因子VIIa形成激活剂时,获得了因子IXa和因子Xa生成的预测速率。在其他实验中,无论有无血小板和/或去内皮兔主动脉,加入高分子量激肽原均未提高因子XIa对因子IX的激活速率。这些动力学数据有力地表明,因子XIa和因子VIIa在因子IX的激活中均发挥着生理上重要的作用。
