Expressioni

Inductioni

Induced by low levels of proline and by osmotic shock. The leader of mgtA mRNA functions as a riboswitch, favoring transcription under low Mg2+ conditions. Under limiting proline levels the MgtL peptide encoded within the mgtA leader cannot be translated, thereby favoring the transcription of the mgtA ORF. Induction by osmotic shock also depends on translational regulation by MgtL (Probable). Induced by low extracellular levels of Mg2+.Curated1 Publication
