malfunction
-
mutant strains H1862 lacking fcf1. The mutant strain produces semirough lipopolysaccharide with only one O unit attached to the core-lipid A moiety while the wild type strain produces normal lipopolysaccharide. The result indicates that fcf1 is required for the synthesis of the O-antigen in Escherichia coli O52
