The gene
Basic information
- Locus tag: BSU15420
Phenotypes of a mutant
Deletion of divIVA leads to filamentation and polar divisions that in turn 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
Extended information on the protein
- Kinetic information:
- Domains:
- Modification: The Mycobacterium DivIVA homologue Wag31 is phosphorylated at T73.
- Cofactor(s):
- Effectors of protein activity:
- Localization: DivIVA forms a ring underneath the invaginating membrane at the site of cell division and is enriched at both cell poles.
