Abstract
  1. Some of the products excreted by cultures of lysine-requiring Escherichia coli A.T.C.C. 12408 grown under lysine-limiting conditions have been studied. 2. A glycolipid designated ;extracellular lipoglycopeptide' was prepared from culture filtrates of such organisms. It contained 35% of lipid, 19% of carbohydrate, 3.4% of P and 3.7% of N. 3. Comparison of the lipids, fatty acids, carbohydrates and amino acids of this lipoglycopeptide with those of whole cells, cell walls and cellular lipopolysaccharides shows that it has few features (except its residual lipids) in common with any of these fractions. 4. The lipoglycopeptide was antigenically related to both walls and lipopolysaccharide.
摘要
  1. 对在赖氨酸限制条件下生长的需要赖氨酸的大肠杆菌A.T.C.C. 12408培养物分泌的一些产物进行了研究。2. 从这些生物体的培养滤液中制备了一种名为“细胞外脂糖肽”的糖脂。它含有35%的脂质、19%的碳水化合物、3.4%的磷和3.7%的氮。3. 将这种脂糖肽的脂质、脂肪酸、碳水化合物和氨基酸与全细胞、细胞壁和细胞脂多糖的脂质、脂肪酸、碳水化合物和氨基酸进行比较,结果表明,除了其残留脂质外,它与这些组分中的任何一种几乎没有共同特征。4. 脂糖肽在抗原性上与细胞壁和脂多糖都有关系。
