title: Pseudomonas diminuta LPS with a new endotoxic lipid A structure.
abstract: Lipid A that contains mainly 2,3-diamino-2,3-dideoxy-D-glucose, phosphate and fatty acids in the molar ratio 2:1:5-6 was found in Pseudomonas diminuta lipopolysaccharide. The lipid A was considered to have a diamino-sugar disaccharide structure that carries a nonglycosidic phosphomonoester group and amide-bound acyloxyacyl and 3-hydroxy fatty acyl groups. The lipopolysaccharide exhibited endotoxic activities including lethal toxicity, pyrogenicity, local Shwartzman activity, body weight-decreasing toxicity and Limulus activity. The free lipid A was also endotoxic.
