Modified cyclic peptides prepared from the corresponding linear peptides by processing with: ^aTruD heterocyclase, which converts Cys to thiazoline, followed by PatGmac; ^bPatD heterocyclase, which converts Cys, Ser, Thr to thiazoline, oxazoline and methyl oxaxoline respectively, followed by PatGmac, ^cMacrocylicization by PatGmac, ^dMicD heterocyclase, which converts Cys to thiazoline, Thr to methyl oxaxoline, followed by PatGmac, followed ArtGox and ^eLynD heterocyclase, which converts Cys to thiazoline, followed by PatGmac and ArtGox.
