Abstract

The inhibition of phospholipid synthesis engendered by starving glycerol 3-phosphate (G3P) auxotrophs of Escherichia coli (plsB or gpsA) for G3P is incomplete; 5 to 10% of the normal rate of phospholipid synthesis remains, even after prolonged starvation. We report that G3P starvation of a strain having lesions in both the gpsA and plsB genes resulted in essentially complete (>98.5%) inhibition of phospholipid synthesis, indicating that all de novo glycerolipid synthesis in E. coli proceeds by acylation of G3P.
