Gram-negative bacteria characteristically are surrounded by an additional membrane layer,
the outer membrane. Although outer membrane components often play important roles in …

Lipopolysaccharide or LPS is localized to the outer leaflet of the outer membrane and serves
as the major surface component of the bacterial cell envelope. This remarkable glycolipid is …

ABSTRACT The PmrA/PmrB regulatory system of Salmonella enterica controls the
modification of lipid A with aminoarabinose and phosphoethanolamine. The …

The outer membrane (OM) is a defining feature of Gram-negative bacteria that serves as a
permeability barrier and provides rigidity to the cell. Critical to OM function is establishing …

Glycomics, the study of microbial polysaccharides and genes responsible for their formation,
requires the continuous development of rapid and sensitive methods for the identification of …

In the Enterobacteriaceae, the outer membrane is primarily comprised of
lipopolysaccharides. The lipopolysaccharide molecule is important in mediating interactions …

Addition of a phosphoethanolamine (pEtN) moiety to the outer 3-deoxy-d-manno-
octulosonic acid (Kdo) residue of lipopolysaccharide (LPS) in WBB06, a heptose-deficient …

Gram-negative bacteria possess an outer membrane envelope consisting of an outer leaflet
of lipopolysaccharides, also called endotoxins, which protect the pathogen from …

The capacity of Neisseria gonorrhoeae to cause disseminated gonococcal infection requires
that such strains resist the bactericidal action of normal human serum. The bactericidal …

In response to the in vivo environment, the Salmonella enterica serovar Typhimurium
lipopolysaccharide (LPS) is modified. These modifications are controlled in part by the two …
