Categories containing this gene/protein

transcription factors and their control, phosphoproteins

This gene is a member of the following regulons

The gene

Basic information

  • Locus tag: BSU34740

Phenotypes of a mutant

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
  • Protein family: HPr family
  • Paralogous protein(s): HPr

Extended information on the protein

  • Kinetic information:
  • Domains: HPr domain (1–85)
  • Modification: phosphorylation on Ser46 by HprK PubMed
  • Cofactor(s):
  • Effectors of protein activity:

Database entries


  • KEGG entry: [2]

Additional information

Crh does not possess the phosphorylation site used for PTS phosphotransfer (His-15 in PtsH), it can only be phosphorylated on Ser-46

Expression and regulation

  • Regulation: very weak stimuation of expression by citrate and succinate PubMed
  • Regulatory mechanism:
  • Additional information: Crh is weakly expressed. This results in part from a poorly conserved ribosomal binding site of the mRNA. PubMed

  • Expression vector:
    • pGP641 (N-terminal Strep-tag, purification from B. subtilis, for SPINE, in pGP380), available in Stülke lab
    • pGP734 (C-terminal Strep-tag, purification from B. subtilis, for SPINE, in pGP382), available in Stülke lab
  • lacZ fusion: see yvcI
  • GFP fusion:
  • two-hybrid system: B. pertussis adenylate cyclase-based bacterial two hybrid system (BACTH), available in Görke lab
