     The authors had proved that one fast-reacting sulfhydryl group also participated in the binding of GST-π with GSH , so that at least 4 different groups were the binding groups of each subunit. The specific modification of amino group by TNBS was also verified and the ionic linkages between GST-π and GSH were proposed.
     作者曾证明GST-π中的一个快反应巯基也参与酶与GSH的结合,故至少有四个不同的基团是酶亚基的结合基团,本文还对TNBS对氨基修饰的特异性作了验证,并讨论了GST-π与GSH结合时形成离子键的情况。

The particularity of crosslinking of ethylene - propylene (EPDM)elastomer has been studied using torque - time curve (at 150℃),equilibrium modulus and swelling, physico - property tests and infraredspectra (MIRIR). The torque of EPDM increases linearly with continually heatingat 150℃ after obtained equilibrium density of chemical crosslinkingwith sulfur, accelereators or DCP. Therefore, the optimum crosslinkingtime can not be obtained with torque - time curve (Viscosmeter), butit can be obtained with equilibrium...

The particularity of crosslinking of ethylene - propylene (EPDM)elastomer has been studied using torque - time curve (at 150℃),equilibrium modulus and swelling, physico - property tests and infraredspectra (MIRIR). The torque of EPDM increases linearly with continually heatingat 150℃ after obtained equilibrium density of chemical crosslinkingwith sulfur, accelereators or DCP. Therefore, the optimum crosslinkingtime can not be obtained with torque - time curve (Viscosmeter), butit can be obtained with equilibrium modulus or equilibrium swelling. This particularity of crosslinking of EPDM is produced by thecontinually chemical reactions of residual free sulfur, accelerators orDCP in EPDM, after formation of chemical crosslinking, and thesereactions produced the bound groups (such as - C=S or [R-O]~-)of polymer chain. The impact resilience of EPDM is independente of crosslinking,while it is characteristic of macromolecular entangement and itsreaction with fillers.

本文提出采用硫黄、促进剂体系和过氧化物体系作交联剂,测定在150℃温度下,各自交联过程中生成物的横键密度(由拉伸平衡模量、最大溶胀测出)和物性,以及红外分光光度计测定其表层(20微米)内的化学基团变化。结果分析证明:国产乙丙弹性体在化学交联过程中,采用测定扭矩变化动力曲线的方法(称硫化仪),不能确定达到平衡模量或平衡溶胀的最佳交联时间。国产乙丙弹性体的交联动力曲线(扭矩—时间)特点,是由于化学交联剂生成横键后,继续参与化学反应,形成聚合物大分子键侧基团等产物的结果:乙丙弹性体的打击回弹性与其交联横键无关,是EPDM聚合物本身及其与填充料形成的缠结点作用的表征。

By using l-ethyl-3-(3-dimethylaminopropyl)-carbodiimide(EDC) ,2,4,6-trinitrobenzylsulfonic acid and diacetyl for the chemical modification of carboxyl,amino and guanido group of human glutathione S-transferase (GST-π) respectively to study the kinetics for inactivation of enzyme revealed that the corresponding moles of inhibitor needed for fully inactivation of the enzyme were 1.0, 1.08, 0.98/enzyme subunit, suggusting that only one mole of carboxyl, amino and quanido group for each participated in the active center of GST-π subunit. The substrate and its analogs, glutatione, S-hexylglutathione and S-octylglutathione, protected GST-π from modification by the above inhibitors and the rate constant of pseudo-first order reaction k1 was remarkably decreased in the presence of these protectors, indicting that carboxyl, amino and guanido groups were involved in the GSH binding site of GST-π. The authors had proved that one fast-reacting sulfhydryl group also participated in the binding of GST-π with GSH , so that at least 4 different groups were the binding groups of each subunit. The specific modification of amino group by TNBS was also verified and the ionic linkages between GST-π and GSH were proposed.

用1-乙基-3-(3-二甲基氨基丙基)-碳二亚胺(EDC),2.4.6.三硝基苯磺酸(TNBS)和丁二酮(DIC)分别修饰人胎盘型谷胱甘肽S-转移酶(GST-π)的羧基、氨基和胍基,研究了酶的失活动力学,发现引起一分子酶亚基全部失活所需抑制剂的分子数分别为1.0、1.08和0.98,提示每亚基只有一个羧基、氨基和胍基参与酶的活性中心。底物及其类似物谷胱甘肽,S-己烷或S-辛烷谷胱甘肽可保护GST-π免受上述抑制剂的修饰,使假一级反应速度常数k_1明显降低,说明羧基、氨基和胍基是GST-π和GSH结合部位的组成基团。作者曾证明GST-π中的一个快反应巯基也参与酶与GSH的结合,故至少有四个不同的基团是酶亚基的结合基团,本文还对TNBS对氨基修饰的特异性作了验证,并讨论了GST-π与GSH结合时形成离子键的情况。
