Comparison of CDK8–5Y6 complex without CycC at a 0 ns and b 200 ns. Two binding modes are observed when CycC is absent, one at 0 ns which is a typical type-I ligand binding mode, and the other at 200 ns which is partially due to loss of the important salt bridge formed between K52 and E66 (red circle in a). c Is a superposition of the two aligned trajectory frames with 0 ns in green and 200 ns in red showing the large conformational changes that occur in CycC’s absence
