Inhibition of colicin e2 activity by bacterial lipopolysaccharide.
Lipopolysaccharide isolated from colicin E2-sensitive Escherichia coli and from "receptor-minus" mutants inhibits the activity of colicin E2. Lipid A and the polysaccharide fraction obtained by mild acid hydrolysis of lipopolysaccharide are inactive either alone or when tested in combination. Periodate oxidation of lipopolysaccharide destroys over 85% of its inhibition activity.
