Abstract
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.
摘要
我们研究了黄色黏球菌聚集和早期发育过程中脂多糖的变化。从甘油诱导和营养生长期间在琼脂上发育的细胞中分离并鉴定了脂多糖。通过气-液色谱-质谱联用技术将一种甲基化氨基糖鉴定为6-O-甲基半乳糖胺。这种新型糖类在琼脂上发育的细胞中含量丰富。
