WaaL is a membrane enzyme that catalyzes the glycosidic bonding of a sugar at the proximal end of the undecaprenyl-diphosphate (Und-PP)-O-antigen with a terminal sugar of the lipid A-core oligosaccharide (OS). This is a critical step in lipopolysaccharide synthesis. We describe here an assay to perform the ligation reaction in vitro utilizing native substrates. © Springer Science+Business Media New York 2013.
