Phenotypes of a mutant

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: binding and concomintant inactivation of SlrA results in release of SinR from the SinR-SlrA complex and subsequent induction of SinR-controlled genes and operons for biofilm formation PubMed, repression of transcription of lytA-lytB-lytC and lytF PubMed
  • Protein family:
  • Paralogous protein(s): SinR

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity: interaction with SinR triggers binding of SlrR to the promoters of lytA-lytB-lytC and lytF, resulting in their repression PubMed
