From: Cellular conditions of weakly chelated magnesium ions strongly promote RNA stability and catalysis

Proposed effects of weakly chelated magnesium on RNA. Illustration of the effects of amino acids and aaCM for RNA. Amino acids alone increase the folding free energy of RNA, either having no effect or destabilizing the RNA. At the same time, aaCM decreases the folding free energy of RNA, stabilizing the RNA and promoting high catalytic activity
