Traceless Ligation of Cysteine Peptides Using Selective Deselenization Traceless Ligation of Cysteine Peptides Using Selective Deselenization Metanis, Norman; Keinan, Ehud; Dawson, Philip E. 2010-09-17 00:00:00 The synthesis of proteins with a fully native sequence is an ongoing challenge in protein chemistry. Native chemical ligation (NCL) approaches have proven to be generally applicable

T1 - Traceless chemical ligation from S -, O -, and N-acyl isopeptides. AU - Panda, Siva S. PY - 2014/4/15. Y1 - 2014/4/15. N2 - Peptides are ubiquitous in nature where they play crucial roles as catalysts (enzymes), cell membrane ion transporters, and … traceless in Chinese | English to Chinese … The traceless Staudinger ligation of azides and phosphines is an effective method to produce an amide bond . 叠氮化合物和膦硫酯的 无 痕施陶 丁格连接反应是一种有效生成酰胺键的方法。 7 The electronic cash is anonymous and traceless. 发行的电子现金具有 Traceless synthesis of ceramides in living cells reveals traceless manner. Using this method, we uncovered the apoptotic effects of several ceramide species and observed differences in their apoptotic activity based on acyl-chain saturation. Additionally, we demonstrate spatiotemporally controlled ceramide synthesis in live cells through photoinitiated lipid ligation. Our in situ lipid ligation Creating Site-Specific Isopeptide Linkages Between An azidonorleucine residue is installed at a desired site in a substrate protein by nonnatural amino acid incorporation, and a phosphinothioester is installed at the C terminus of a pendant protein by expressed protein ligation. Then, the traceless Staudinger ligation is used to link the substrate and pendant proteins via an isopeptide bond.
