Thus, proteins do not work in isolation. To affect cellular functions, proteins often require one or more cofactors or binding partners, and they must be able to recognize this particular partner from the wide array of molecules present within the cell. For example, a small molecule may bind in the active site to facilitate enzyme catalysis, or a protein may need to specifically recognize and bind a glycan on the surface of a target protein to either direct or inhibit an immune response. Biological function is not a property of a protein alone; it is a property that emerges due to coordinated effort of multiple “players” within a cell.\u003C\u002Fp>\n\n\n\n\u003Cp>Initially, structure-based, generative protein design tools were similar. The protein design problem was broken down into distinct steps that each tackle a more approachable problem. For example, the first stage of the design pipeline generated a generic backbone, often referred to as a scaffold, that represents a protein binder. Initially, these backbones were protein only, leaving important biological context, such as interacting ligands or nucleic acids, out of the picture. Then, the second stage of design was to assign a sequence to the scaffold. In order to identify if a sequence was a good candidate, the third stage may then predict the structure using \u003Ca href=\"https:\u002F\u002Fdeepmind.google\u002Fscience\u002Falphafold\u002F\" target=\"_blank\" rel=\"noreferrer noopener\">AlphaFold\u003C\u002Fa> or \u003Ca href=\"https:\u002F\u002Fopenfold.io\u002F\" target=\"_blank\" rel=\"noreferrer noopener\">OpenFold\u003C\u002Fa>, comparing the predicted structure to the generated scaffold. If prediction and scaffold agree, the design was thought to be of higher quality and more likely to bind the target. Overall, this approach included multiple simplifications to make the protein design task computationally tractable and to release a protein design tool quickly, even if it could not cover every scenario. Despite such simplifications, initial generative protein design tools were able to successfully design de novo protein binders. However, these simplifications limited what scientists could attempt to design and how quickly they could generate new candidates.\u003C\u002Fp>\n\n\n\n\u003Cp>Today, computational biologists can design \u003Cem>de novo\u003C\u002Fem> binders and redesign existing binders to modulate protein-protein interactions through integrated workflows in \u003Ca href=\"https:\u002F\u002Fwww.3ds.com\u002Fproducts\u002Fbiovia\u002Fdiscovery-studio-simulation\" target=\"_blank\" rel=\"noreferrer noopener\">BIOVIA Discovery Studio Simulation\u003C\u002Fa> on the \u003Cstrong>3D\u003C\u002Fstrong>EXPERIENCE platform so long as the design context contains only proteins composed of the standard 20 amino acids. Those workflows have proven very useful to our users, but they also raise the next questions: What if the ligand is part of the design? What if they could design an enzyme around the substrate, or a protein built to engage one specific small molecule and nothing else?\u003C\u002Fp>\n\n\n\n\u003Ch2 class=\"wp-block-heading\" id=\"a-model-that-designs-the-whole-arrangement-1\">\u003Cstrong>A Model That Designs the Whole Arrangement\u003C\u002Fstrong>\u003C\u002Fh2>\n\n\n\n\u003Cp>RFD4-Proteína, a deep learning framework developed at the \u003Ca href=\"https:\u002F\u002Fwww.ipd.uw.edu\u002F2026\u002F06\u002Fcustom-computing-for-the-next-generation-of-protein-design\u002F\">Institute for Protein Design with NVIDIA\u003C\u002Fa>, is the next generation of protein design. Proteins, cyclic peptides, ligands, glycans and nucleic acids are all represented in the design task, so the chemistry around the protein is part of the design. Sequence and structure are generated together, not one after the other, which means the model can settle what a residue \u003Cem>is\u003C\u002Fem> and where it sits as one decision.\u003C\u002Fp>\n\n\n\n\u003Cp>For scientists, the practical effects are the ones that matter.
