The gene
Basic information
- Locus tag: BSU15390
Phenotypes of a mutant
- perturbation of the formation of properly formed division septa
- less efficient cell division results in longer cells. Electron microscopy reveals strongly distorted division septa.
- the sepF mutation in combination with a constitutively active form of WalR (WalR-R204C) results in the formation of cell wall-less L-forms PubMed
- the sepF mutation is synthetically lethal in combination with an ezrA mutation or an ftsA mutation PubMed
