Expression and regulation
- Regulation:
- 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

- 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): 340 PubMed
- number of protein molecules per cell (complex medium with amino acids, without glucose): 2740 PubMed
