本研究的目的是提供进一步的证据,凝血酶原自缔合的化学交联评估。当凝血酶原或片段1的自缔合(通过与二硫代双(琥珀酰亚胺基丙酸酯)共价交联来评价)在相同摩尔浓度的蛋白质下进行评价时,对于任一蛋白质观察到类似的二聚体形成速率。当凝血酶原和片段1与交联剂和钙离子一起孵育时,除了凝血酶原二聚体和片段1二聚体之外,还观察到由凝血酶原和片段1组成的异源二聚体。用凝血酶原1进行的类似实验既未显示出显著的自缔合作用,也未显示出对凝血酶原自缔合作用的影响。凝血酶原片段1异源二聚体形成与片段1对凝血酶原激活因子Xa的影响的比较表明,片段1的抗凝活性不仅仅是凝血酶原和片段1之间形成异源二聚体的结果。
The purpose of the current study is to present further evidence for prothrombin self-association as assessed by chemical crosslinking. When the self-association (evaluated by covalent crosslinking with dithiobis(succinimidylpropionate)) of prothrombin or fragment 1 was evaluated at the same molar concentration of protein, similar rates of dimer formation were observed for either protein. When prothrombin and fragment 1 were incubated together with the crosslinking reagent and calcium ions, a heterodimer consisting of prothrombin and fragment 1 was observed in addition to prothrombin dimer and fragment 1 dimer. Similar experiments with prethrombin 1 showed neither significant self-association nor effect on prothrombin self-association. Comparison of the formation of prothrombin fragment 1 heterodimer formation with the effect of fragment 1 on prothrombin activation by factor Xa suggests that the anticoagulant activity of fragment 1 is not solely a result of the formation of a heterodimer between prothrombin and fragment 1.
