Ligase-controlled cyclo-oligomerization of peptides

A biomimetic one-step ligase-catalyzed cyclo-oligomerization mediated by butelase 1, an Asn/Asp-specific ligase, is introduced that is time-, concentration-, length-, and sequence-dependent. This reaction yields cyclic mono-, di-, tri-, and tetramers from peptide precursors containing 3-15 amino aci...

description A biomimetic one-step ligase-catalyzed cyclo-oligomerization mediated by butelase 1, an Asn/Asp-specific ligase, is introduced that is time-, concentration-, length-, and sequence-dependent. This reaction yields cyclic mono-, di-, tri-, and tetramers from peptide precursors containing 3-15 amino acids ended with Asn and a His-Val tail. The cyclomonomers were favored when the peptide lengths were >9 amino acids. A turn-forming Pro residue at the P2 position favored the formation of higher-order cyclo-oligomers.
