Description

This is a throwback puzzle to the early days of Foldit. The function of this thermophilic protein is unknown, but it is unusual among intracellular proteins in that the native structure includes disulfide bonds. This protein contains six cysteine residues that are oxidized to form three disulfide bonds. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.

Ran my 1207 test script on puzzle 1213 in main, with cysteines banded and filter off; crashed during wiggle after half an hour. No error in log.txt.

The crashes aren't a surprise, since crashes with disulfide bridges have not been fixed yet. Unfortunately, the old version of the client won't work with this puzzle. Puzzle 1213 has a Rama map, which means old clients can't open it.

The only possible workaround is to avoid making any disulfide bridges until late in the game. If disulfides form, you may be able to break them by moving the sidechains apart. Freezing the sidechains should prevent the bridges from re-forming.
