  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification: phosphorylated on ser/ thr/ tyr PubMed
  • Cofactor(s):
  • Effectors of protein activity:
  • Interactions:
  • Localization:

Database entries

  • Structure:
  • Swiss prot entry:
  • KEGG entry: [3]
  • E.C. number:

Additional information

Expression and regulation

  • Regulation: induction by acetate (AlsR) PubMed, repressed as long as terminal electron acceptors are available for respiration (Rex) 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: 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:
