The puzzle has constraints on three disulfide bridges.
The bridges are:
127,139 120,134 133,143
The constraints are invisible if the bridges are in place. They only become visible if you move the sidechains apart to break the bridge.
You see the three bridges in here:
The red constraint lines appear when the cysteine sidechains are in a different position:
Zooming in a bit:
Constraints are like strong bands. They can't be deleted or disabled, and there's no way to change the strength.
