1The E Protein Is a Multifunctional Membrane Protein of SARS-CoV显示文摘The E (envelope) protein is the smallest structural protein in all coronaviruses andis the only viral structural protein in which no variation has been detected. Weconducted genome sequencing and phylogenetic analyses of SARS-CoV. Based ongenome sequencing, we predicted the E protein is a transmembrane (TM) pro-tein characterized by a TM region with strong hydrophobicity and α-helix con-formation. We identified a segment (NH2-_L-Cys-A-Y-Cys-Cys-N_-COOH) in thecarboxyl-terminal region of the E protein that appears to form three disulfide bondswith another segment of corresponding cysteines in the carboxyl-terminus of the S(spike) protein. These bonds point to a possible structural association between theE and S proteins. Our phylogenetic analyses of the E protein sequences in all pub-lished coronaviruses place SARS-CoV in an independent group in Coronaviridaeand suggest a non-human animal origin.QingfaWu YilinZhang HongLu JingWang XimiaoHe YongLiu ChenYe WeiLin JianfeiHu JiaJi JingXu JiaYe YongwuHu WenjunChen SonggangLi JunWang JiauWang ShengliBi HuanmingYang 2003Genomics, Proteomics & Bioinformatics2003,1,2:2
2Extraction of Cesium from the Irradiated Nuclear Waste by 4(5),4'(5')-Bis[1-hydroxyalkylbenzo]-21-crown-7显示文摘Bis[1-hydroxyalkylbenzo]-21-crown-7 (A-C) have been synthesized by ) two-step reactions from dibenzo-21-crown-7 (DB21C7). Extraction of cesium cation from nitric acid solutions by A-C has been investigated in nitromethane. Under the conditions of various concentration of HNO3 or NaNO3, the extractabilities of A and B were superior to that of DB21C7.YingDU WenJunCHEN ShengYingQIN 2004Chinese Chemical Letters2004,15,10:1
