Chemical ligation can be extended to biologically expressed proteins enabling the semisynthesis of proteins of unlimited size that contain fluorophores or cross-linking agents at defined positions. Our goal is to introduce non-coded amino acids and other chemical groups into proteins to better understand the molecular basis of protein function.

By program-ming self-assembly motifs into leaving groups, we envision that these molecular fragments can act as traceless topological modiﬁers, templating the topology of the polymer network before they are expelled during gelation.

Traceless β-mercaptan-assisted activation of valinyl Introduction. Native chemical ligation (NCL) is one of the most powerful and frequently used methods employed in the fields of chemistry and chemical biology1 for the construction of polypeptides and proteins.2 The versatility of the approach has encouraged continued development of surrogates, or “masked forms” of the required peptidyl thioesters,3 such as peptidyl hydrazide,4 peptide N Chemical ligation from O-acyl isopeptides via 8- and 11 General Papers ARKIVOC 2014 (iv) 91-106 Page 91 ©ARKAT-USA, Inc Chemical ligation from O-acyl isopeptides via 8- and 11-membered cyclic transition states Siva S.

The Staudinger-Bertozzi ligation : Bertozzi developed the Staudinger-then-aza-Wittig reaction shown below and demonstrated its utility in ligating large phosphorescent compounds by the amide bond. This reaction is high yielding and highly chemoselective, offering possibilities for applications in various chemical biology researches. Chemistry and Biochemistry Selected Publications .
