Acyl Transfer
Acyl Transfer — The movement of an acyl group from one molecule to another, the fundamental chemical event in peptide bond formation during synthesis.
What Is Acyl Transfer?
Acyl transfer is a chemical reaction in which an acyl group (R-CO-) is transferred from a donor to an acceptor. Peptide bond formation is fundamentally an acyl transfer: the activated carboxyl of one amino acid transfers its acyl group to the amino group of another. In native chemical ligation, an initial S-to-N acyl transfer rearrangement converts a thioester intermediate to a native peptide bond.
Applications
- SPPS coupling: Activated amino acid transfers acyl group to resin-bound amine
- NCL: Transthioesterification followed by S-to-N acyl shift creates native peptide bond
- Sortase: Enzymatic acyl transfer at LPXTG motif for site-specific conjugation
