Questions & Answers

Here is a place to post questions and answers for each other about how to do things in Proteopedia. Here are some from me and previous students.

• For step-by-step instructions on creating example scenes, try Proteopedia:DIY:Scenes.
• Safari currently not working for making a scene... LKT 2/27 But it just worked for Xuni! Test saving a simple scene first.

• A very useful color scheme is "chain" which colors separate proteins or DNA strands in different colors (first select all protein or DNA).

• To show the biological unit, follow directions at Biological Unit: Showing. The pdb file will display the "asymmetric unit" = the smallest unit that can be replicated to generate the full crystal. Example: the protein may function as a dimer (you need biochemical experiments to tell you this -- crystallography and NMR won't tell you), but the pdb file may display a monomer (if the dimer is symmetric) or two dimers (if they have slightly different conformations in the crystals -- perhaps due to crystal contacts or perhaps representing 2 functional states of the protein!).

• Anyone know what format we should be putting our references in?

For references, follow the format used in the example on the Asp receptor and they will be put in automatically. You just find out the PMID code (listed in pubmed for example) and insert it into the following, at the place where you want the reference cited (click edit to see what is actually inserted here). ^[1] You also need to add the section:

References

• Hey guys this is just a useful tip:

If you get an xml error after you try to save your changes it is due to the green scene coding. Our group experienced this issue and it would not let us access our sandbox. In order to fix this go back (or find the page to edit in your history) and delete the green scene code that was just entered. Then save the page and you should be back to your sandbox. This may be trivial to many, but just throwing it out there.

• To highlight some interesting portion of your protein:

Under the selections tab, you can "limit to residue numbers." So for example enter in 60-65, then click "replace selection" below. Then if you go to the colors tab you can pick a color for just the residues you have selected. If it is a loop or if they are hard to see you can go to the representation tab and set selection to ball and stick or spacefill.

It is also useful to click the "selection halos:" box under the picture. That shows you what you have in your selection.
