Spo0A regulon

The gene

Basic information

  • Locus tag: BSU35250

Phenotypes of a mutant

  • a ftsX mutation is synthetically lethal with a lytE mutation (due to a lack of autolysin activity) PubMed
  • shorter, fatter cells, this can be rescued by addition of Mg(2+) PubMed
  • reduced growth rate, especially at low Mg(2+) concentrations PubMed

Database entries

  • DBTBS entry: [1]
  • SubtiList entry: [2]

Additional information
