The gene

Basic information

  • Locus tag: BSU13660

Phenotypes of a mutant

deletion of kinD suppresses the sporulation defect of matrix mutants, while its overproduction delays sporulation PubMed

Database entries

  • DBTBS entry: no entry
  • SubtiList entry: [1]

Additional information

Categories containing this gene/protein

protein modification, transcription factors and their control, phosphorelay, membrane proteins, phosphoproteins

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • autophosphorylation, phosphorylation of Spo0F, regulates the onset of sporulation by inhibiting the activity of Spo0A until matrix, or a component therein, is sensed PubMed
    • dual role as a phosphatase or a kinase, activity is linked to the presence of extracellular matrix in the biofilms PubMed
    • mainly active in the younger, outer regions of a colony (with KinC) PubMed
  • Protein family:
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains: two transmembrane segments, C-terminal histidine phosphotransferase domain
  • Modification: autophosphorylation on a His residue
  • Cofactor(s):
  • Effectors of protein activity:
  • Localization:
