Abstract

The conformation of bacitracin A, a widely used cyclic dodecapeptide antibiotic in aqueous solution, has been investigated using 500 MHz 1H NMR and molecular modeling. Findings revealed that a region (residues 1-6) is folded over the cyclic ring, resulting in metal coordination sites, a thiazoline ring, and Glu4 and His10 being proximate to each other.
