Biological Sciences
Many recent theoretical and experimental techniques have been developed to probe the structurefunction relationships of complex biomolecules. The roles of RNAs are dependent upon various intricate structural motifs and interactions, including hairpins, pseudoknots, long range territory contacts, bulges and internal loops, that are not easily captured by these methods. We had previously developed an enhanced replica exchange molecular dynamics method that incorporated secondary structure information in the form of distance restraints in order to effectively overcome kinetic barriers and sample conformational space. In several structures, restrained RNA base pairs near large bulges displayed a preference for stacking over hydrogen bonding …
