Superposition of the AA3266 conformations found in simulations with MOR and NK1R (A) Focus on the Tyr-d-Ala-Gly-Phe-fragment, (B) Focus on the -NH-NH-Z-d-Trp fragment. Green sticks represent the structures from simulations with MOR, and pink sticks represent the structures from simulations with NK1R. The reference structures are MOR-1 for (A) and NK1-a for (B) as the most populated clusters at the respective receptors.
