We report an enzymatic cyclization strategy termed omniligase-mediated peptide bicyclization. An electrophilic group was introduced into the recognition sequence of omniligase to achieve intramolecular bicyclization with Cys residues. In combination phage display, we identified a bicyclic ligand targeting TEAD4 KD value 1.5 μM, 100-fold lower than its linear version, demonstrating utility this platform for discovering ligands.

ABSTRACT The secondary structure plays a crucial role in the biological activity of peptides. Various strategies have been developed to stabilize particular peptide conformations, including sequence modifications and macrocyclization approaches. Often, interplay between conformational constraint flexibility is central bioactivity. Here, we investigate how α‐helicity influences enzymatic head‐to‐tail cyclization using an engineered Sortase. We show that peptides with low helicity readily undergo intramolecular cyclization, while more rigid, helical exhibit complex behaviors cyclic dimer formation. These findings reveal increased rigidity can redirect reactions from intermolecular processes, demonstrates changes molecular guide chemical reactivity. insights advance design peptide‐derived materials, hydrogels, stimuli‐responsive probes.
