Identification and functional characterization of an ABC transport system involved in polysaccharide export of A-band lipopolysaccharide in Pseudomonas aeruginosa.

Abstract excerpt

Pseudomonas aeruginosa coexpresses two distinct lipopolysaccharide (LPS) molecules known as A band and B band. B band is the serospecific LPS, while A band is the common LPS antigen composed of a D-rhamnose O-polysaccharide region. An operon containing eight genes responsible for A-band polysaccharide biosynthesis and export has recently been identified and characterized (H. L. Rocchetta, L. L. Burrows, J. C....
