The gene

Basic information

  • Coordinates:

Phenotypes of a mutant

Deletion of divIVA leads to filamentation and polar divisions that cause a minicell phenotype. A divIVA mutant has a severe sporulation defect.

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: DivIVA is required for polar localisation of MinCD via MinJ. It also recruits RacA to the distal pole of the prespore.
  • Protein family: gpsB family (according to Swiss-Prot)
  • Paralogous protein(s): GpsB
