Inhibition of d-Ala incorporation into wall teichoic acid in Staphylococcus aureus by desleucyl-oritavancin†
Abstract
The mode of action for desleucyl-oritavancin was investigated by adding an antibiotic to Staphylococcus aureus during its growth in a defined medium containing L,D-[1-15N]Ala and L-[1-13C]Lys, or D-[1-15N]Ala. 13C{15N} and 15N{13C} rotational-echo double resonance NMR determined that desleucyl-oritavancin inhibited the incorporation of D-[1-15N]Ala into wall teichoic acid.
