The gene

Basic information

  • Locus tag: BSU01780

Phenotypes of a mutant

essential PubMed

Database entries

  • DBTBS entry: no entry
  • SubtiList entry: [1]

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: L-glutamine + D-fructose 6-phosphate = L-glutamate + D-glucosamine 6-phosphate (according to Swiss-Prot)
  • Protein family:
  • Paralogous protein(s):

Extended information on the protein

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

Database entries

  • Structure:HIV (from Bacillus subtilis, 100% identity) PubMed
2VF4 (GlmS from E. coli, 39% identity, 58% similarity) PubMed
    • the ribozyme: 3G8S, 3G9C, 3G8T, 3G95, 3G96 (all for the ribozyme from Bacillus anthracis), 2HO7 (the ribozyme from Thermonanaerobacter tengcongensis)
  • KEGG entry: [2]

Additional information

  • subject to Clp-dependent proteolysis upon glucose starvation PubMed

Expression and regulation

  • Regulation:
    • repressed by glucosamine, N-acetylglucosamine, N-propionylglucosamine or N-formylglucosamine PubMed
    • glmS is only expressed in the absence of glucosamine 6-phosphate (glmS ribozyme)
  • Regulatory mechanism: glmS ribozyme: glucosamine 6-phosphate binds the leader mRNA, and a riboswitch with ribozyme activity cleaves off the glmS section from the mRNA, resulting in stopp of transcript elongation
  • Additional information:

Biological materials

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