In vivo evidence for the involvement of anionic phospholipids in initiation of DNA replication in Escherichia coli.

Xia, W, Dowhan, W

In vitro, anionic phospholipids can reactivate inactivated DnaA protein, which is essential for initiation of DNA replication at the oriC site of Escherichia coli [Sekimizu, K. & Kornberg, A. (1988)...

Phosphatidylinositol cannot substitute for phosphatidylglycerol in supporting cell growth of Escherichia coli.
