  • Title: Peptidoglycan Composition in Neisseria.
    Author: Schaub RE, Dillard JP.
    Journal: Methods Mol Biol; 2019; 1997():111-120. PubMed ID: 31119621.
    Abstract:
    The composition of Neisseria peptidoglycan has been of scientific interest for over four decades. Initial investigations focused on discovering the mechanisms causing rising rates of antibiotic resistance in N. gonorrhoeae by determining differences in peptidoglycan composition in penicillin susceptible and resistant strains. The discovery that cytotoxic peptidoglycan fragments are also released by Neisseria furthered the interest in peptidoglycan composition. This method describes the purification, enzymatic degradation, and separation of peptidoglycan fragments by high-performance liquid chromatography (HPLC). It also describes the preparation of samples so that they can be positively identified by mass spectrometry.
