|Description:||Design a symmetric trimer, with 3 identical chains that assemble together! This puzzle includes a Secondary Structure Objective so that no more than 50% of residues may form helices. We're taking a short break from H-bond Networks, but we have a new (optional) challenge for Foldit players! The starting structure includes several helices and sheets placed in a suggested arrangement, similar to a TIM barrel (but with 9 strands instead of 8). This is a hypothetical fold that nobody has been able to design yet, but we think Foldit players may have some ideas! Note that the started arrangement is only a rough placement, we expect players will have to do some considerable refolding to create a high-scoring design. For such a fold to work, it's important that the sheets of one subunit will need to pair with the symmetric sheets on either side, so that the entire barrel forms a continuous and circular hydrogen-bonded sheet!|
