We determined the chemical structure of lipoteichoic acid (LTA) from Lactobacillus gasseri JCM 1131(T). The repeating unit was comprised of glycerolphosphate and 2-alanylglycerolphosphate. The glycolipid anchor was tetrahexosylglycerol with two or three acyl groups. To our knowledge, this is the first demonstration of a tetrahexose structure in an LTA glycolipid anchor.
我们确定了源自干酪乳杆菌 JCM 1131(T)的脂磷壁酸(LTA)的化学结构。重复单元由甘油磷酸和 2-丙氨酰基甘油磷酸组成。糖脂锚由带有两个或三个酰基的四己糖甘油组成。据我们所知,这是首次在 LTA 糖脂锚中证明四己糖结构。
