چکیده

The occurrence of 2-keto-3-deoxy-D-manno-octonic acid (KDO) in lipopolysaccharides (LPS) of Vibrio parahaemolyticus was demonstrated for the first time by gas chromatography-mass spectrometry after dephosphorylation, reduction, and methylation. KDO was virtually completely phosphorylated, since no KDO was detected by either gas chromatography or thiobarbituric acid assay before dephosphorylation. The level of KDO in all six strains of V. parahaemolyticus investigated ranged from 0.37 to 0.69%, which was considerably lower than that in enterobacterial LPS.

Chemical characterization of the lipopolysaccharides from enteropathogenic Escherichia coli O142 and O158.

Lipopolysaccharides (LPS) from two enteropathogenic strains of E. coli O142 and O158 were isolated by hot phenol-water extraction procedure. Polyacrylamide gel electrophoretic pattern of the LPS showed the typical ladder like pattern of smooth type of LPS. The LPS of E. coli O158 was found to contain L-rhamnose, D-glucose and N-acetyl-D-galactosamine as major constituents together with D-galact...

Bordetella pertussis waaA encodes a monofunctional 2-keto-3-deoxy-D-manno-octulosonic acid transferase that can complement an Escherichia coli waaA mutation.

Bordetella pertussis lipopolysaccharide (LPS) contains a single 2-keto-3-deoxy-D-manno-octulosonic acid (Kdo) residue, whereas LPS from Escherichia coli contains at least two. Here we report that B. pertussis waaA encodes an enzyme capable of transferring only a single Kdo during the biosynthesis of LPS and that this activity is sufficient to complement an E. coli waaA mutation.

Lipopolysaccharide was prepared from the extracellular lipoglycopeptide produced by the lysine-requiring mutant Escherichia coli A.T.C.C. 12408 grown under lysine-limiting conditions. The lipid moiety, containing glucosamine phosphate and four fatty acids (lauric acid, myristic acid, beta-hydroxymyristic acid and palmitic acid) corresponded in composition to lipid A of known bacterial lipopolys...
