Abstract
Lipid composition of E. coli membranes and cells in conditions of repression, derepression and constitutive synthesis of alkaline phosphatase is studied. The identity of qualitative composition of phospholipids and neutral lipids in these conditions is demonstrated. Derepressed and constitutive enzyme syntheses are correlating, a certain increase of phosphatidylglycerol in the total phospholipid pool being more pronounced in cells, than in membranes. The enzyme synthesis correlates also with the increase of 14C-label incorporation into lipids.
摘要
研究了大肠杆菌膜和细胞在碱性磷酸酶阻遏、去阻遏和组成型合成条件下的脂质组成。证明了这些条件下磷脂和中性脂质定性组成的一致性。去阻遏和组成型酶合成相关，细胞中总磷脂池中磷脂酰甘油的一定增加比膜中更明显。酶合成也与脂质中14C标记掺入的增加相关。
