Polytheonamide

WebA prominent example is polytheonamide A, which exhibits numerous post-translational modifications, some of which were unknown in ribosomal peptides until recently. Among these post-translational modifications, C-methylations have been proposed to be catalyzed by two putative radical S-adenosylmethionine (rSAM) enzymes, PoyB and PoyC. WebPolytheonamide B (1) is an ion-channel forming natural peptide with a d, l-alternating 48 amino acid sequence, which is an exceedingly potent cytotoxin.We recently designed and …
