Tailed bacteriophages and herpesviruses have a DNA "pipe" in their capsids, called a portal protein[1]. The images here depict 7sya, a homo-dodecamer[1]. In the animation at right, each of the 12 protein chains is colored amino to carboxy spectrum (N->C Rainbow):
| N | C |
All images show a model simplified to alpha carbons only. Except for the top row, the alpha carbons are rendered at an exaggerated diameter (6.0 Å) to give a solid appearance. All images and the animation were generated with FirstGlance in Jmol, most using color schemes available under Solid (Views tab). The two faces of the oblate structure (or tube with a flange) are designated the N-face (face with amino termini) and the C-face (face with carboxy termini).
