T. Ito et al., IDENTIFICATION OF A NOVEL SUGAR, 4-AMINO-4,6-DIDEOXY-2-O-METHYLMANNOSE IN THE LIPOPOLYSACCHARIDE OF VIBRIO-CHOLERAE O1 SEROTYPE OGAWA, Carbohydrate research, 256(1), 1994, pp. 113-128
A novel sugar in the lipopolysaccharide of Vibrio cholerae O1 serotype
Ogawa has been identified. The sugar was liberated from the lipopolys
accharide 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-methylman
nose (2-O-methylperosamine). Since it was found only in the lipopolysa
ccharide of Vibrio cholerae O1 serotype Ogawa, it seems that the sugar
is one of the specific constituents determining Ogawa serotype specif
icity.
