Contents
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
filamentation is suppressed by minCD mutations
The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity: DivIVA is required for polar localisation of MinCD via MinJ. PubMed It also recruits RacA to the distal pole of the prespore PubMed.
- Protein family: gpsB family (according to Swiss-Prot)
- Paralogous protein(s): GpsB
Extended information on the protein
- Kinetic information:
- Domains: The first 60 amino acids constitute a lipid binding domain. PubMed
Multimerisation involves two coiled-coil motifs, one in the lipid binding domain, and the other one being present in the helical C-terminal domain PubMed.
- Modification: The Mycobacterium DivIVA homologue Wag31 is phosphorylated at T73 PubMed.
- Cofactor(s): not known
- Effectors of protein activity: not known
- Localization: DivIVA forms a ring underneath the invaginating membrane at the site of cell division and is enriched at both cell poles PubMed.
