Abstract

Heterocycle-containing cyclic peptides are promis-ing scaffolds for the pharmaceutical industry but their chemicalsynthesis is very challenging. A new universal method has beendevised to prepare these compounds by using a set ofengineered marine-derived enzymes and substrates obtainedfrom a family of ribosomally produced and post-translation-ally modified peptides called the cyanobactins. The substrateprecursor peptide is engineered to have a non-native proteasecleavage site that can be rapidly cleaved. The other enzymesused are heterocyclases that convert Cys or Cys/Ser/Thr intotheir corresponding azolines. A macrocycle is formed usinga macrocyclase enzyme, followed by oxidation of the azolinesto azoles with a specific oxidase. The work is exemplified by theproduction of 17 macrocycles containing 6–9 residues repre-senting 11 out of the 20 canonical amino acids
