For future reference, this is technically not the place to ask for official rule clarifications, but according to the clarifications posted here and here, your statement about the prebuild should be correct. Any other structures (i.e. amino acids, highlights of specific sites on the protein, etc.) you decide to include on your model can be considered for extra bonus points, and for those, I recommend you read the papers that these proteins are based on (posted on the MSOE CBM website), because that can help you get started, and what you opt to do can be anything your mind so desires to do.So according to the rules clarifications, the pre-build is only the Anti-Crispr protein right? Are there any other structures we should include?
