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
