We have cloned a gene from a Salmonella typhimurium with the ability to complement the rfaC mutation (heptose-deficient lipopolysaccharide, sensitivity to rough-specific bacteriophages, and susceptibility to hydrophobic antibiotics). A 1018-base pair

Gram-negative bacterial septicemia is a common clinical syndrome resulting, in part, from the activation of phagocytic leukocytes by LPS. By using flow cytometry, we have characterized LPS-induced expression of the beta 2 integrin CD11b/CD18. After e

Tumor necrosis factor (TNF) released by lipopolysaccharide (LPS)-stimulated mononuclear phagocytes is a critical mediator of sepsis. We examined the capacities of rough mutant Salmonella typhimurium LPS (Rc) and LPS partial structures lipid A, monoph

Attachment of the cationic sugar 4-amino-4-deoxy-l-arabinose (l-Ara4N) to lipid A is required for the maintenance of polymyxin resistance in Escherichia coli and Salmonella typhimurium. The enzymes that synthesize l-Ara4N and transfer it to lipid A h

Lipid A of Salmonella typhimurium can be resolved into multiple molecular species. Many of these substances are more polar than the predominant hexa-acylated lipid A 1,4'-bisphosphate of Escherichia coli K-12. By using new isolation methods, we have

Polymyxin-resistant mutants of Escherichia coli and Salmonella typhimurium accumulate a novel minor lipid that can donate 4-amino-4-deoxy-l-arabinose units (l-Ara4N) to lipid A. We now report the purification of this lipid from a pss(-) pmrA(C) mutan

Regulated covalent modifications of lipid A are implicated in virulence of pathogenic Gram-negative bacteria. The Salmonella PhoP/PhoQ-activated gene pagP is required for resistance to cationic antimicrobial peptides and for biosynthesis of hepta-acy

Chlamydia trachomatis lipid A is unusual in that it is acylated with myristoyl chains at the glucosamine 3 and 3' positions. We have cloned and expressed the gene encoding UDP-N-acetylglucosamine 3-O-acyltransferase of C. trachomatis (CtlpxA), the fi
