The biosynthesis of goadvionins—hybrid lipopeptide antibiotics—is not fully understood. An unusual acyltransferase, GdvG, has now been identified and shown to catalyse a condensation reaction between an acyl-carrier-protein-tethered very-long-chain fatty acid and an eight-residue ribosomally synthesized and post-translationally modified peptide. The position of functional groups in the very-long acyl chain have been determined by tandem mass spectrometry.
