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
