CRYSTAL STRUCTURE OF COMPLEX BETWEEN ELECTRON TRANSFER PARTNERS

在2.8E电子流中有一些微弱的特征 CcP：cc（H）复合物的密度图，我们想进一步研究 仔细 CcP：cc（Y）和CcP：cc（H）的接口应该非常小。 对研究电子转移很重要。 似乎疏水性 和货车德瓦尔斯相互作用是保持 CcP：cc（Y）。 分子间只有一个弱氢键存在， CcP：cc（Y）结构，与CcP：cc（H）复合物相比，CcP：cc（H）复合物具有三个 分子间氢键，其中两个是电荷介导的。 但 比较CcP：cc（Y）和CcP：cc（H）接口并不容易， 使用从不同分辨率极限延伸到的数据。 我们希望 获得更精细的结构，这可能有助于定位其 位置更准确。

There are a few weak features in the current 2.8 E electron density map of CcP:cc(H) complex we would like to examine more closely. The interfact of CcP:cc(Y) and CcP:cc(H) should be very important for study of electron transfer. It appears that hydrophobic and van der Waals interactions are the predominant forces holding the CcP:cc(Y). Only one weak intermolecular hydrogen bond exists in the CcP:cc(Y) structure, in contract to CcP:cc(H) complex, which has three intermolecular hydrogen bonds, two of which are charge-medicated. But it is not easy to compare interface between CcP:cc(Y) and CcP:cc(H) using data extending to from different resolution limits. We hope to obtain a more highly refined structure which may help locate its position more accurately.
