formation of lipid A disaccharide from UDP-GlcNAc and lipid X, i.e. 2,3-diacylglucosamine 1-phosphate, releasing UDP. Lipid X, i.e. 2,3-diacylglucosamine 1-phosphate, bears two R-3-hydroxymyristoyl chains in Arabidopsis thaliana and is a key precursor of lipid A. No other lipid X molecular species are detected
