Ramachandran plots for all protein systems in the current study. Generally, the top left quadrant is beta sheets, and the bottom left quadrant is alpha helices. The gradient ranges from brown to blue-green; brown shows angles that are favored in the Titan environment, and blue-green shows angles that are favored in the Earth environment. In the Titan environment, the phi angle remains similar to the Earth environment, but the psi angle shifts from -50 degrees to -25 degrees.
