What does the color information represent in the image?
- flobosg 6y agoSuch color schemes usually represent the position of the amino acid in the protein sequence, from blue (start, or N-terminus) to red (end, or C-terminus). Keep in mind that the figure shows an oligomer of apoferritin, formed by several individual protein chains.
- natechols 6y agoIt's also possible it's colored by uncertainty in the atomic positions - what crystallographers call the "B-factor".
- flobosg 6y agoThat is true, but B-factors are mostly shown in a ribbon, cartoon, or "putty" (e.g. https://www.researchgate.net/figure/B-factor-diagram-of-protomeric-OmpU-represented-by-the-B-factor-putty-program-in-PyMOL_fig2_322190994 https://www.researchgate.net/figure/B-factor-diagram-of-prot...) representation, not as ball-and-sticks.
- aendruk 6y agoLooks like it's just distance from the center, probably for the sake of visualizing 3D space in a press release.
- flobosg 6y agoThat's another plausible option that I forgot to consider.
