Occurrence of 2,3-Diamino-2,3-dideoxy-D-glucose in Lipid A from Lipopolysaccharide of Pseudomonas diminuta

Abstract
A phosphorylated disaccharide of glucosamine forms the backbone of lipid A of lipopolysaccharides in most gram-negative bacteria. This glucosamine is replaced by 2,3-diamino-2,3-dideoxy-D-glucose in lipid A from P. diminuta and probably in that from P. vesicularis.
