Oscillations in the synthesis of cell wall components in synchronized cultures of Escherichia coli.
The rate of cell wall synthesis with respect to both proteins and lipids was determined in synchronized cultures of Escherichia coli B/r. Whereas the rate of total protein synthesis showed an exponential increase with cell age, the rate of incorporation of proteins and lipids into cell wall had a maximum at a cell age of 30 to 35 min, 15 min before cell division. This oscillation was observed in both the cytoplasmic membrane and in the outer membrane of the cell envelope.
