Metalloregulator
Protein-based transcription factors that sense intracellular metal concentrations and regulate gene expression accordingly. Metalloregulators are the decision-making layer of bacterial metal homeostasis -- they read the labile metal pool, determine whether a specific me…

Riboswitch
Structured RNA elements in the 5' untranslated region (UTR) of bacterial mRNAs that directly sense small molecules -- including metal ions -- and regulate gene expression without any protein intermediary. Where metalloregulators are the protein-based metal sensors, ribo…
