Jul 17, 2018 · The salicylaldehyde group is released spontaneously during the reaction, resulting in the traceless formation of ceramide, without the introduction of any extraneous chemical moieties (Fig. 1A). From these initial experiments, we found that compound 3 offered superior hydrolytic stability, showing very little degradation (<2%) over 16 h (Fig. 1B

O-acyl peptides in traceless chemical ligation reactions is sup-ported by theoretical and computational studies. Further ligation. investigations on other sized transition sta tes as well as Herein, we report a traceless ligation at Val-Xaa sites under mild thiol additive-free reaction conditions, whereby the introduction of β-mercaptan on the C-terminal valine residue effectively activates the otherwise unreactive N-acyl-benzimidazolinone (Nbz), and enables the use of a one-pot ligation–desulfurization strategy to generate the 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 structural elements (proteins) within biological systems.

EnzyTag technology Our technology offers an entry into linear and cyclic peptide drugs, small proteins, (bio)conjugates, Antibody Drug Conjugates, PROTACs and LYTACs.

Research - Menard Lab Our traceless chemical ligation strategy enables the labeling of target proteins while maintaining their innate function, thereby alleviating functional perturbations associated with common molecular biology techniques. It is thus perfectly suited to deliver biophysical reporter probes and to characterize the interaction of proteins in real Traceless | Definition of Traceless at Dictionary.com Traceless definition, having or leaving no trace: a traceless crime.
