Characterization of a Lactobacillus gasseri JCM 1131T Lipoteichoic Acid with a Novel Glycolipid Anchor Structure

摘要

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.
