Categories containing this gene/protein

carbon core metabolism

This gene is a member of the following regulons

AlsR regulon, Rex regulon, stringent response

The gene

Basic information

  • Locus tag: BSU36010

Phenotypes of a mutant

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: 2 pyruvate = 2-acetolactate + CO2 (according to Swiss-Prot)
  • Protein family: TPP enzyme family (according to Swiss-Prot)

Extended information on the protein

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

Database entries

  • Structure:
  • KEGG entry: [3]

Additional information

Expression and regulation

  • Regulation:
    • induction by acetate (AlsR) PubMed
    • repressed as long as terminal electron acceptors are available for respiration (Rex) PubMed
    • subject to positive stringent control upon lysine starvation PubMed

Note: since acetate formation requires ackA activation by CcpA there is an indirect effect of CcpA on the alsSD operon: the operon is not expressed in ccpA mutants

  • Regulatory mechanism:
    • stringent response: due to presence of adenines at +1 and +2 positions of the transcript PubMed
    • AlsR: transcription activation in the presence of acetate PubMed
    • Rex: transcription repression if the ratio NADH2/NAD is high PubMed
  • Additional information:

Biological materials

  • Mutant:
  • Expression vector:
  • lacZ fusion:
  • GFP fusion:
  • two-hybrid system:
  • Antibody:
