FoldCheck has real 3D proteins now. Today I started building the actual interactive side of FoldCheck. I installed Mol* into the project and created a separate React component for the molecular viewer. I then connected that component to FoldCheck and built the first version of the 3D protein workspace. There were a few problems getting Mol* working with the project, mainly incorrect import paths and getting the package to work properly with Vite. After debugging those, I managed to load 1CRN, a real protein structure from the Protein Data Bank, directly inside FoldCheck. The structure is now fully interactive, I can rotate it, zoom in and explore it in 3D. The current Mol* controls are only temporary. I also decided that the finished FoldCheck won’t just be one massive scrolling page. Searching for a protein will eventually open a dedicated analysis workspace with separate sections for the 3D structure, confidence, PAE, geometry and experimental comparison. Next I’m going to turn this basic viewer into that proper workspace and start connecting FoldCheck to real AlphaFold prediction data.
