Abstract
  1. Cell walls of Pseudomonas aeruginosa were prepared and analysed. 2. Separate preparations were found to be reproducible, e.g. the phosphorus contents of all batches lay in the range 2.0-2.1%. 3. Ninhydrin-positive compounds in hydrolysates accounted for 43-46% of the cell wall and 79-87% of the nitrogen of the cell wall. Examination of the results for individual ninhydrin-positive compounds showed that 5-15% of the cell wall was murein and about 30% protein. 4. Trypsin treatment of crude cell-wall preparations preferentially liberated arginine, lysine and leucine, but it was not clear whether these arose from cell-wall or cytoplasmic proteins.
摘要
  1. 制备并分析了铜绿假单胞菌的细胞壁。2. 发现不同的制备物具有可重复性,例如所有批次的磷含量在2.0 - 2.1%范围内。3. 水解产物中茚三酮阳性化合物占细胞壁的43 - 46%,占细胞壁氮的79 - 87%。对单个茚三酮阳性化合物的结果检查表明,细胞壁的5 - 15%是胞壁质,约30%是蛋白质。4. 用胰蛋白酶处理粗制细胞壁制剂时,优先释放出精氨酸、赖氨酸和亮氨酸,但尚不清楚这些是来自细胞壁蛋白还是细胞质蛋白。
