Folding Forum

in the rotating picture of the protein viewer what do the different colored spheres represent - I suspect the while ones are hydrogen because there are me most but cannot speculate on the others - not a chemist, more of stats person - thanks

You're spot on for the hydrogen. I found the other colors in the viewer source code (lines 128-154).

• Carbon - dark grey
• Hydrogen - light grey
• Nitrogen - blue
• Oxygen - red
• Sulfur - yellow
• Other - purple

thanks for the prompt reply and for the link to all the color coding - really useful - mpj

Gr8 - So left off is the rest of the amino acid & shows bonding site/interaction? The bonding of atoms, is stable/predictable, but order of amnio acids, somewhat random or DNA specific. So it's bonding (building protein) that drives folding, creating twists & torque, till stable state, equals no folding? If so could controlled de-naturing mis-folded proteins, reveal error folding, compared to proper folded protein? Folding power would then be Krebs cycle dependent?
