▪ Abstract Bacterial lipopolysaccharides (LPS) typically consist of a hydrophobic domain
known as lipid A (or endotoxin), a nonrepeating “core” oligosaccharide, and a distal …

Lipopolysaccharide O antigens are important virulence determinants for many bacteria. O-
antigen synthesis is an interesting problem in cell-surgace assembly. There are two known …

Publisher Summary This chapter provides an overview of the molecular mechanisms
involved in synthesis and expression of cell-surface polysaccharides in Gram-negative …

Lipopolysaccharide (LPS) genes have many of the characteristics of PAIs but also differ in
significant ways. Lipopolysaccharide differs from the products of most PAI genes in that it is …

We previously showed that the product of the wbaP gene of Salmonella enterica serovar
Typhimurium has two functions: it is involved in the first step of O-antigen synthesis (the …

The group 1 K30 antigen from Escherichia coli (O9a: K30) is present on the cell surface as
both a capsular structure composed of high‐molecular‐weight K30 polysaccharide and as …

A series of polyprenyl phosphates with modified structure of polyprenyl residue was
prepared through phosphorylation of polyprenyl trichloroacetimidates with phosphoric acid …

ABSTRACT d-Galactan I is an O-antigenic polymer with the repeat unit structure [→ 3)-β-d-
Gal f-(1→ 3)-α-d-Gal p-(1→], that is found in the lipopolysaccharide of Klebsiella …

Publisher Summary This chapter describes the biosynthesis of bacterial polysaccharide
chains composed of repeating units. A number of complicated polymers having chains …

The 6.6-kb rfb gene cluster from Klebsiella pneumoniae serotype O1 (rfbKpO1) contains six
genes whose products are required for the biosynthesis of a lipopolysaccharide O antigen …
