An empirical molecular docking study of a di-iron binding protein with iron ions

Various molecular docking software packages are available for modeling interactions between small molecules and proteins.However,there have been few reports of modeling the interactions between metal ions and metalloproteins.In this study,the AutoDock package was employed to example docking into a di-iron binding protein,bacterioferritin.Each binding site of this protein was tested for docking with iron ions.Blind docking experiments showed that all docking conformations converged into two clusters,one for internal iron binding in sites within the metalloprotein and the other for external iron binding on the protein surface.Local docking experiments showed that there were significant differences between two internal iron binding sites.Docking at one site gave a reasonable root-mean-square deviation(RMSD) distribution with relatively low binding energy.Analysis of the binding mode quality for this site revealed that more than half of the docking conformations were categorized as having good binding geometry,while no good conformations were found for the other site.Further investigations indicated that coordinating water molecules contributed to the stability of binding geometries.This study provides an empirical approach towards the study of molecular docking in metalloproteins.

Microcomputer Applications

Application of Improved BP Neural Network in Forecasting Grain Yield （ 1 ） WU Yan, DU Dong（Business School of Hohai University, Nanjing 210098, China） Abstract： Cause for slow convergence about the traditional BP neural network are analyzed, and an improved BP algorithm is proposed in this paper. Moreover, we develop a forecast model of time sequence object on this basis, and then this model is studied on the Grain Yield in Jiangsu Province with Matlab. The results from the simulation test proved that the algorithm is feasible and practicable.     

微软教你作英文

“毫不夸张地说,我对英库渴望已久。”微软亚洲研究院自然计算组副研究员刘晓华在采访快结束时才对记者说了一句很“私人”的感受。。我是一个中国人,在微软亚洲研究院,我的日常语言变成了英语,日常口头交流还好说,但是发邮件,演示PPT、写研究论文就需要精益求精。这样特定的角色就要求我像美国人一样写出纯正,地道的英文来。”     

文化产业需要巧实力

巧实力并不是巧克力的笔误。美国最近提出巧实力,一查英文,原来是smart power,smart为个词,其实一般不译成巧,但也没有很好的词与之准确对应。IBM将其译成智慧,如智慧地球（Smart Planet）。smart也经常被译为聪明。但我认为。smart最传神的意思是灵,灵具有聪明和灵活两方面的含义。人是万物之灵,就是因为人既聪明,又灵话。
