Summary
Mutants have reduced OM vesiculation (McBroom, 2006). [More information is available at EcoGene: EG11339]. The lipopolysaccharide of Escherichia coli K-12 consists of two major components: the hydrophobic lipid A moiety inserted into the outer membrane and the phosphorylated core oligosaccharide . [More information is available at EcoCyc: EG11339].
