  • Effectors of protein activity

  • activity is stimulated by GlmR [pubmed|30248093]
  • Structure

  • [PDB|2VF4] (GlmS from ''E. coli'', 39% identity, 58% similarity) [Pubmed|18295797]
  • the ribozyme: [PDB|3G8S], [PDB|3G9C], [PDB|3G8T], [PDB|3G95], [PDB|3G96] (all for the ribozyme from ''Bacillus anthracis''), [PDB|2HO7] (the ribozyme from ''Thermonanaerobacter tengcongensis'')
  • [SW|Localization]

    additional information

  • ''glmS'' is only expressed in the absence of glucosamine 6-phosphate ([SW|GlmS ribozyme])
  • glucosamine 6-phosphate binds the leader mRNA, and a [SW|riboswitch] with [SW|ribozyme] activity cleaves off the [gene|4E23D2043D51C587027ABBF6335F148295E90B8F|glmS] section from the mRNA, resulting in stopp of transcript elongation
