[edit] DNAClamp

The assembled human DNA clamp, a trimer of the protein PCNA, which is a processivity factor that increases the speed and efficiency of DNA replication. In the assembled replication complex, the clamp encircles the DNA, which passes through the central pore.

I think this image is nice looking, interesting and enclopedic. It is a DNA clamp rendered by user Opabinia regalis using VMD ([1]) modeling software.

    • Support edit 1 I guess encyclopedic value beats eye candy. Still cool though - Ravedave (help name my baby) 14:02, 10 October 2006 (UTC)

  • Support, would strongly support if any useful labels are added. --BRIAN0918 03:53, 3 October 2006 (UTC)
  • Unfortunately there isn't really much to label. The most obvious and useful improvement would be to show the actual PCNA-DNA complex, but unfortunately the two molecules have not been co-crystallized. I added some explanatory text to the caption to give a better sense of what this thing does outside the context of the articles. Opabinia regalis 05:01, 3 October 2006 (UTC)
  • Comment - I can see no reason to have the multiple colors on this image. If the goal is to show the individual domains, wouldn't it would be more informative to show the individual trimers in either three different colors or to have the equivalent sections of each of the trimers in the same colors? This could alternatively be done by adding labels to the individual trimers. Also, svg would be nice. InvictaHOG 05:33, 3 October 2006 (UTC)
    • I tend to agree about the domains, as is - the colour look neat, but doens't actually add anything informative to the image.--Peta 01:00, 4 October 2006 (UTC)
  • It's colored by atom index, which honestly is mostly used for visual effect, but in this case I liked the way it highlights the pseudohexagonal symmetry, which is an unusual feature of these molecules. I'm not aware of a way to convert a raytraced image to SVG - it can be rendered even larger, but surely there's a point at which file size and scaling artifacts become a problem?

  • FWIW I uploaded an alternative version colored by polypeptide chain. Opabinia regalis 01:32, 4 October 2006 (UTC)
