List of Unknown/Unsolved proteins

I have a suggestion to make:

What if we post here some unknown/unsolved proteins, so that players could try to take the challenge in Sandbox mode?
I couldn't find a place with known primary structure but unsolved secondary, tertiary (or even quaternary) structure.

Here's some great information that player MrZanav shared during the last office hours: You can search the UniProt database of proteins with known sequences, using various filters. This is a search that finds reviewed proteins of length 100 to 150: https://www.uniprot.org/uniprot/?query=length%3A%5B100+TO+150%5D+AND+reviewed%3Ayes&sort=score

It brings up page 1 of a list containing ~61,000 proteins of that length. How do you know which ones are solved? Click on the Entry column (on the left) for a particular protein. It will take you to that protein's page. Hit Ctrl-F to find text on the page, type pdb and hit Enter. If the protein has a PDB ID, the protein is solved. If there is no PDB ID found on the page, the protein is not solved (or at least not yet published).

How do you get the sequence? In the left hand column there are blue boxes with checkboxes. Click the one that says "sequence." It will display the sequence, and if you look just above that display box, there is a link to FASTA, which is a simpler format for copying the sequence.

What if you want shorter or longer proteins? Change the filter terms in the above link, or in the search bar at the top of the list page in UniProt.
