在非繁殖期高密度大沙鼠种群中,我们研究了胁迫以及幼年雄鼠的性激素浓度、腹中腺大小和体重对社群中成体(≥1年龄)存在的依赖性。

The structures of menoquinone MQ1, ubiquinone UQ1 and their radical anions are optimized by both the semiempirical AM1 and density functional theory [B3LYP/6-31G] methods.

用量子化学半经验的AM1和密度泛函DFTBELYP/6-31G(d方法分别优化了质体醌MQ1、泛醌UQ1及其阳离子自由基的结构。

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.

除了对各个电子传递体( FAD ,[2Fe-2S],[4Fe-4S],[3Fe-4S]以及血红素分子)进行精确定位外,我们在该结构跨膜区靠近线粒体基质一端的口袋 Qp 中,发现了一些电子密度,认为是所结合的辅酶 Q 的头部结构,这一点被与抑制剂结合的复合体的结构所证明,在该结构中, 2- TTFA 恰好结合在口袋 Qp 中,同时,我们还发现了第二个2- TTFA 的结合位点,位于跨膜区靠近线粒体膜间隙一端的口袋 Qd 中,这个发现具有全新的意义,将影响人们对电子在复合物 II 中传递以及辅酶 Q 在复合物 II 与 III 之间转移的认识,促使人们重新复合物 II 在线粒体呼吸链中的角色。
