WebInitially, a new thioester bond is formed by transthioesterification involving attack by the sulfhydryl group of the N-terminal cysteine residue on the C-terminal thioester. The transitory ligation product then undergoes a spontaneous S-N acyl rearrangement from a thioester to a stable peptide bond. WebNative chemical ligation involves reactions that are very similar to intein splicing and peptide ligation found in certain protein expression systems. A peptide having a C-terminal thioester reacts with an N-terminal cysteine residue in another peptide to undergo a transthioesterification reaction, which results in the formation of an intermediate thioester … gutter cleaners athens alabama https://billmoor.com
