Intramolecular Enzymatic Peptide Synthesis: Trypsin-mediated Coupling of the Peptide Bond between B22-Arginine and B23-Glycine in A Split Crosslinked Insulin

Abstract: The resealing of a split peptide bond [OC(Met) 2 ] was 55-60%, and reproducible yields (B22/23) in a crosslinked insulin derivative by a of OC(Met) 2 -insulin were 40%. After removing trypsin-mediated coupling reaction in Tris buffer/ the crosslink and purification, crystalline resynglycerol/dimethylsulphoxide 1:1:1 at pH 6.5 is thesized insulin of high biological activity was described. The coupling yield obtained with obtained in a yield of 43% and an overall yield, i ,A reB29 -(carbonyl-bis-methionyl) insul… Show more
