Additional information

• subject to Clp-dependent proteolysis upon glucose starvation PubMed

Expression and regulation

• Operon: ybbP-ybbR-glmM-glmS

• Sigma factor:

• Regulation: 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

• Mutant:

• Expression vector:

• lacZ fusion:

• GFP fusion:

• two-hybrid system:

• Antibody:
