An altered FtsA can compensate for the loss of essential cell division protein FtsN in Escherichia coli.

Molecular microbiology - 1 Jun 2007

Abstract excerpt

FtsN is the last known essential protein component to be recruited to the Escherichia coli divisome, and has several special properties. Here we report the isolation of suppressor mutants of ftsA that allow viability in the absence of ftsN. Cells producing the FtsA suppressors exhibited a mild cell division deficiency in the absence of FtsN, and no obvious phenotype in its presence. Remarkably, these altered FtsA...
