This gene is a member of the following regulons

Spo0A regulon

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. PubMed A divIVA mutant has a severe sporulation defect. PubMed

Database entries

• DBTBS entry: [1]

• SubtiList entry: [2]

Additional information

Filamentation is suppressed by mutations in minCD PubMed.

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.

The DivIVA from Streptococcus pneumoniae is phosphorylated at a threonine side chain by the Ser/Thr protein kinase Sktp1. PubMed

• Cofactor(s): not known

• Effectors of protein activity: not known

• Interactions:
  • (MinC-MinD)-MinJ-DivIVA PubMed
  • DivIVA-RacA, DivIVA-DivIVA
  • Maf-DivIVA PubMed

• Localization:
  • DivIVA forms a ring underneath the invaginating membrane at the site of cell division and is enriched at both cell poles PubMed.
  • forms rings at the division septum and patches at the cell poles PubMed
