Why PAR is not RNA: ion atmospheres, bridging interactions, and ion-induced structural collapse
Lipika Baidya, Heyang Zhang, Hung T Nguyen
This study develops a coarse-grained model of PAR and uses molecular dynamics to show PAR undergoes stronger structural transitions than RNA in response to divalent ions due to preferential ion binding and bridging.
