The gene

Basic information

  • Locus tag: BSU25690

Phenotypes of a mutant

  • sporulates at a higher frequency
  • will sporulate in the presence of replication stress

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: Sda is a checkpoint protein that is upregulated in response to replication stress PubMed. Sda inhibits the autokinase activity of KinA (and likely KinB as well). This in its turn results in reduced levels of Spo0A~P. Thus, replication stressed cells will not initiate sporulation.
  • Protein family:
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:
  • Localization:

Database entries

  • KEGG entry: [3]
  • E.C. number:

Additional information

Sda is rapidly turned over by the ClpP/X system because of some uncharged residues at its C-terminus PubMed.

Expression and regulation
