| Abstract |
Inactivation of pgsA, which is responsible for biosynthesis of anionic phospholipid phosphatidylglycerol (PG), was shown to affect biosynthesis and secretion of alkaline phosphatase (PhoA) in Escherichia coli. A decrease in PG, but not in total anionic phospholipids, correlated with reduction of PhoA secretion, suggesting the role of PG in this process. A dramatic decrease in PG (from 18 to 3, but not 8, percent of the total phospholipids) inhibited not only secretion, but also synthesis of PhoA. In addition, pgsA inactivation expedited repression of PhoA synthesis by exogenous orthophosphate. |
