L-Fucosamine and 4-Oxo-norleucine as Constituents in Mucopolysaccharides of Certain Enteric Bacteria

THE presence of D -fucosamine (2-amino-2,6-dideoxy- D -galactose) in materials of bacterial origin 1 was first established in 1958. This amino sugar was isolated from a lipo-polysaccharide obtained from Chromobacterium violaceum (N.C.T.C. 7917) and has been detected in a few other strains of Rhizobi...

Description
Summary:THE presence of D -fucosamine (2-amino-2,6-dideoxy- D -galactose) in materials of bacterial origin 1 was first established in 1958. This amino sugar was isolated from a lipo-polysaccharide obtained from Chromobacterium violaceum (N.C.T.C. 7917) and has been detected in a few other strains of Rhizobiaceae. D -Fucosamine 2 has also been found in Bacillus cereus of the family Bacillaceae 3 . On the other hand, L -fucosamine (2-amino-2,6-dideoxy- L -galactose) has been obtained from the capsule of Diplococcus pneumoniae type V of the Lactobacillaceae 4 . This communication concerns the isolation of L -fucosamine from a mucopolysaccharide obtained from Citrobacter freundii 05 : H 30 of the Enterobacteriaceae. Thus, L -fucosamine is found for the first time in a Gram-negative bacterium.
