Sweetening Cyclic Peptide Libraries

Abstract

Enzymatic macrolactamization of linear glycosidated peptides provides access to an important class of drug-like molecules. The work presented in this issue [1] shows that it may be possible to make complex libraries of glycosidated cyclic peptides by incorporating glycosidated amino acids into linear peptides via solid-phase peptide synthesis followed by thioesterase-mediated peptide cyclization.
