Categories containing this gene/protein

utilization of specific carbon sources, transcription factors and their control, phosphoproteins

This gene is a member of the following regulons

The MtlR regulon:

The gene

Basic information

  • Locus tag: BSU04160

Phenotypes of a mutant

Database entries

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

Additional information

The protein

Basic information/ Evolution

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

Extended information on the protein

  • Kinetic information:
  • Domains: N-terminal DNA-binding domains, two PTS-regulation domains (PRD1 and PRD2), EIIB (Gat)-like domain, EIIA (Mtl)-like domain
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:
    • activity is stimulated by PtsH-dependent phosphorylation in PRD2 (mechnism of carbon catabolite repression) PubMed
    • activity is inhibited by MtlF-dependent phosphorylation in the EIIB(Gat)-like domain on Cys-419 (this prevents activity in the absence of mannitol and allows induction in presence of mannitol) PubMed

Database entries

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