Categories containing this gene/protein

biofilm formation

This gene is a member of the following regulons

AbrB regulon, RemA regulon, SinR regulon

The gene

Basic information

  • Locus tag: BSU24620

Phenotypes of a mutant

  • altered cell death pattern in colonies PubMed

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: forms amyloid fibers that bind cells together in the biofilm PubMed

Additional information

Expression and regulation

  • Additional information:
    • induction by sequestration of SinR by SinI or SlrA PubMed or by SlrR PubMed
    • the tapA-sipW-tasA operon is not expressed in a ymdB mutant PubMed
    • the amount of the mRNA is substantially decreased upon depletion of RNase Y (this is likely due to the increased stability of the sinR mRNA) PubMed
