Abstract
Mg2+-Responsive riboswitches represent a fascinating example of bifunctional RNAs that sense Mg2+ ions with high selectivity and autonomously regulate the expression of Mg2+-transporter proteins. The mechanism of the mgtA riboswitch is scarcely understood, and a detailed structural analysis is called for to study how this RNA can selectively recognize Mg2+ and respond by switching between two alternative stem loop structures. In this work, we investigated the structure and Mg2+-binding properties of the lower part of the antiterminato
