Identification of a novel sugar, 4-amino-4,6-dideoxy-2-O-methylmannose in the lipopolysaccharide of Vibrio cholerae O1 serotype Ogawa.
A novel sugar in the lipopolysaccharide of Vibrio cholerae O1 serotype Ogawa has been identified. The sugar was liberated from the lipopolysaccharide when hydrolyzed in 10 M HCl at 90 degrees C for 15 min. The sugar was purified and identified as 4-amino-4,6-dideoxy-2-O-methylmannose (2-O-methylperosamine). Since it was found only in the lipopolysaccharide of Vibrio cholerae O1 serotype Ogawa, it seems that the sugar is one of the specific constituents determining Ogawa serotype specificity.
