A phosphorylated 3-deoxy-manno-octulosonic acid (KDO) was released from the lipopolysaccharide (LPS) of the deep rough mutant (Rb+169) of Haemophilus influenzae by acid hydrolysis. Both phosphorylated and dephosphorylated KDO, produced by treatment with alkaline phosphatase, were identified by gas chromatography-mass spectrometry after trimethylsilylation. This technique provides a rapid and reliable method for the identification of phosphorylated KDO in LPS.
通过酸水解从流感嗜血杆菌深度粗糙突变体(Rb + 169)的脂多糖(LPS)中释放出磷酸化的3-脱氧甘露糖辛酮酸(KDO)。用碱性磷酸酶处理产生的磷酸化和去磷酸化的KDO,在三甲基硅烷化后通过气相色谱 - 质谱法进行鉴定。该技术为鉴定LPS中的磷酸化KDO提供了一种快速可靠的方法。
