News from Greece

Hi Eran, actually I was on vacation after the summer school of Erice! The last days I'm back in the lab and try to find the rythm of the experiments ;) I shown to my boss the proteopedia and my page..he is excited! Actually I'm writing a paper and I may use the proteopedia for making the pictures. I would like to ask you how can I export the pictures to my pc. We'll be in contact..you'll see the progress of my page!

best wishes Maria

Hi Eran, Now back at home with access to my Mac. Much enjoyed meeting and talking with you. Carole and I enjoyed our round trip of Sicily, and we more or less walked our feet off in Pompei last Monday. Off to practice our golf swings now. I also talked to one of the head honchos of the Cambridge small molecule crystallographic database, and he was receptive to the idea of making a filterered subset of drugs and other biologically-active small molecules available to Proteopedia (read: ligands). If you are ever in the neighbourhood of Basel, look us up, and we can offer you a free place to sleep. best regards Trevor

Bad green link

Eran, I have a green link which does not work, it should make a Ramachandran plot. When I attempt to edit it the SAT freezes and no other scenes can be loaded. In fact as I remember when I first made the scene the SAT froze. After the SAT freezes some of the links above and below this bad link no longer work. Is there a way that a developer can delete scenes?

Karl

After I left the message for you, I decided to take a different approach and not use the link, but I would be interested in knowing what is wrong with the link if you can discover that. I named the link plot_tripep_disallowed.

PDBsum site

Eran, After exploring this site I have come to the conclusion that the entry page to this site changes from time to time. Is that correct? If so, I should give directions on the Ramachandran page how to generate the Ramachandran plot on PDBsum.

By the way that site is a wonderful resource. I am going to include it in the computer resource exercise that I have my Biochemistry I students do.

Eran, I just realized that I was not thinking clearly this morning. I had forgotten that the url that I am using is coded for 1eve and Procheck, and therefore the site will open with the desired protein and information displayed.

Proteopedia for teaching

Hi Eran

I'm in the middle of my labs using Proteopedia, and on balance I think it's a great improvement for this class - I run 6 streams of 60 students each in a 2nd year biochemistry class. Using sPDBv meant that they spent a lot of time struggling with the program, but proteopedia is letting them just think about the protein structure instead. So, overall positive. However, two things that have come up:

1) Secondary structure definitions - How does Jmol generate them? Are they user definable? Jmol is clearly using a different algorithm to sPDBv, so students are seeing inconsistency when they use both routes. (For the record, I agree with sPDBv's pick!)

2) More seriously, the display of backbone hydrogen bonds is wrong - not sure if this is something I'm doing wrong or a fault in Jmol. Backbone hydrogen bonds are being drawn between C-alphas rather than between carbonyl oxygens and peptide nitrogens. Check out the link at the very bottom of the page http://www.proteopedia.org/wiki/index.php/User:J._Shaun_Lott/BIOSCI_203 marked "What is wrong with this picture?" to see what I mean.

cheers!

What to do with my students contributions

Hi Eran,

I am trying user talk to communicate instead of my email, since my question may be relevant to other educators. I have several student contributions that I wish to keep and others that ought to be erased eventually. I want to keep the good ones, and one bad one for illustration of a range of student abilities. I am not sure if its best to transfer the material to my page; start another page with student contributions, or to link to the student's pages. I have the passwords the student sites, so I can access the scripts. What do you suggest is best?
