OpgE is the OPG biosynthetic transmembrane phosphoethanolamine transferase responsible for adding the phosphoethanolamine substituents to the OPG backbone in the periplasm (Bontemps-Gallo, 2013). Osmoregulated periplasmic glucans (OPGs) were originally called membrane-derived oligosaccharides opgE(ybiP) mutants do not have defects in LPS structure as determined by mass spectrometery, indicating that OpgE(YbiP) modifies a substrate other than LPS (Klein, 2013).
