A tuberculin-active glycopeptide containing eight different amino acids and glucose was isolated from the protoplasm of Mycobacterium tuberculosis. A molecular weight of 4,000 to 5,000 was established by Sephadex gel filtration; other analyses showed a peptide to carbohydrate ratio of 9:1. These observations suggest a tentative composition of 3 to 4 residues of glucose, 12 residues each of aspartic and glutamic acids, 3 residues each of lysine, glycine, and serine, and 1 residue each of arginine, threonine, and alanine.
从结核分枝杆菌的原生质中分离出一种含有8种不同氨基酸和葡萄糖的具有结核菌素活性的糖肽。通过葡聚糖凝胶过滤确定其分子量为4000至5000;其他分析表明肽与碳水化合物的比例为9:1。这些观察结果提示其初步组成为3至4个葡萄糖残基、天冬氨酸和谷氨酸各12个残基、赖氨酸、甘氨酸和丝氨酸各3个残基以及精氨酸、苏氨酸和丙氨酸各1个残基。
