"CPK" stands for Corey-Pauling-Koltun. It commonly refers to spacefilling physical molecular models developed by Corey, Pauling and Koltun[1][2] in the 1950's and 1960's. CPK also refers to the color scheme for the elements that they adopted. CPK Color Scheme for the ElementsIn this color scheme, carbon is gray or black, oxygen is red, nitrogen is blue, sulfur is yellow, and hydrogen is white. As an example, to the right you see selenocysteine and then you can change its rendering with the green links below: Another example, heme C: CPK in JmolThe command "color cpk" applies this color scheme in popular molecular visualization programs such as RasMol, Chime, and Jmol. The complete set of element colors used by Jmol is available at Jmol Colors, where the colors used by RasMol are compared with those used by Jmol. The CPK color scheme for the elements is also incorporated into a standard set of color schemes for macromolecules, DRuMS. CPK in ProteopediaA color key such as the one below can be inserted into Proteopedia using existing templates (see Help:Color Keys):
