title: Molecular cloning and characterization of a locus responsible for O acetylation of the O polysaccharide of Legionella pneumophila serogroup 1 lipopolysaccharide.
abstract: Complementation experiments, Tn5 mutagenesis, and DNA sequencing were used to identify a locus (lag-1) that participates in acetylation of Legionella pneumophila serogroup 1 lipopolysaccharide. Nuclear magnetic resonance analyses of lipopolysaccharides from mutant and complemented strains suggest that lag-1 is responsible for O acetylation of serogroup 1 O polysaccharide.
