Effects of Mg2+ on the free energy landscape for folding a purine riboswitch RNA.

Biochemistry - 12 Apr 2011

Leipply Desirae, Draper David E

Abstract excerpt

There are potentially several ways Mg2+ might promote formation of an RNA tertiary structure: by causing a general "collapse" of the unfolded ensemble to more compact conformations, by favoring a reorganization of structure within a domain to a form with specific tertiary contacts, and by enhancing cooperative linkages between different sets of tertiary contacts. To distinguish these different modes of action, we...
