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:
    • subject to Clp-dependent proteolysis upon glucose starvation PubMed
    • A ncRNA is predicted between glmM and glmS PubMed
    • number of protein molecules per cell (minimal medium with glucose and ammonium): 2000 PubMed
    • number of protein molecules per cell (complex medium with amino acids, without glucose): 4000 PubMed
