Role of ligand binding in structural organization of add A-riboswitch aptamer: a molecular dynamics simulation.

Abstract excerpt

The specific binding of ligands is the first step of gene expression or translation regulation by riboswitches. However, understanding the mechanism of the specific binding is still difficult because the tertiary structures of the riboswitch aptamers are available almost only for ligand-bound state at present. In this paper we hope to give some insights into this problem through the studies of the role of...
