In growing cultures of Escherichia coli, the nonacylated glycerol of phosphatidylglycerol (PG) is labeled more rapidly than is the acylated glycerol. This is, in part, due to a rapid exchange reaction of the nonacylated glycerol. Only some of the PG molecules undergo this reaction while others are stable. Using a mutant unable to make glycerophosphate, we have shown that the nonacylated glycerol of PG can exchange with non-phosphorylated glycerol.
在大肠杆菌的生长培养物中,磷脂酰甘油(PG)的非酰化甘油比酰化甘油标记得更快。这部分是由于非酰化甘油的快速交换反应。只有部分PG分子会发生这种反应,而其他分子则是稳定的。通过使用无法合成甘油磷酸的突变体,我们已经表明PG的非酰化甘油可以与非磷酸化甘油进行交换。
