Figure 3: Correlation networks of apo and bound riboswitches.
From: Dynamics Correlation Network for Allosteric Switching of PreQ1 Riboswitch

(A) Apo-riboswitch. One node represents a nucleotide. The strength of the edge is defined as the absolute value of the inter-node correlation between two nodes. Different colors represent different secondary domains. Nodes with degree larger than four have been marked with its nucleotide names. The size of node represents the value of degree. (B) Bound riboswitch.
