Novel change in the carbohydrate portion of Myxococcus xanthus lipopolysaccharide during development.
We have examined the alterations in lipopolysaccharide during aggregation and early development in Myxococcus xanthus. The lipopolysaccharide was isolated and characterized from cells developing on agar during glycerol induction and vegetative growth. A methylated amino sugar was identified as 6-O-methylgalactosamine by gas-liquid chromatography-mass spectrometry. This novel sugar was enriched in cells developing on agar.
