Dr. KP takes you on a journey into an actual protein crystal structure. From the individual amino acids through the tertiary structure, interactively explore the macromolecules that are carrying out and the chemical reactions and essential cellular functions keeping you alive right now. I’ve added some cool “extras” to the 2D video: some photos from my protein crystallography days, and images and annotations better explain some of the renderings.
