Extracellular Mg21 controls the activation of the Salmonella PhoP/PhoQ regulatory system. One of the adaptive responses driven by PhoP/PhoQ includes the transcriptional induction of mgtA and mgtCB, which encode two P-type Mg21 regulatory system. One of the adaptive responses driven by PhoP/PhoQ includes the transcriptional induction of mgtA and mgtCB, which encode two P-type Mg21 regulatory system.

Mg21 also controls mgtA expression by a riboswitch located in its 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both 21 also controls mgtA expression by a riboswitch located in its 50-untranslated region (50UTR). In this work, it was shown that the 50UTR of both0-untranslated region (50UTR). In this work, it was shown that the 50UTR of both mgtA and mgtCB is responsible for a fine-tuned Mg21-dependent regulation of these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA and mgtCB is responsible for a fine-tuned Mg21-dependent regulation of these genes. Evidence was also provided that the Mg21 riboswitch targets the mgtA21 riboswitch targets the mgtA transcript for degradation by RNase E when cells are grown in high Mg2121 environments.
