Supramolecular Interactions of Teixobactin Analogues in the Crystal State.

ABSTRACT: This Note presents the X-ray crystallographic structure of the N-methylated teixobactin analogue N-Me-d-Gln₄,Lys₁₀-teixobactin (1). Eight peptide molecules comprise the asymmetric unit, with each peptide molecule binding a chloride anion through hydrogen bonding with the amide NH group of residues 7, 8, 10, and 11. The peptide molecules form hydrogen-bonded antiparallel β-sheet dimers in the crystal lattice, with residues 1-3 comprising the dimerization interface. The dimers further assemble end-to-end in the crystal lattice.
