Discussion with Markus Buehler: Transforming Coronavirus and Artificial Intelligence-engineered proteins into melodies
In a groundbreaking development, researchers have used artificial intelligence (AI) to sonify the spike protein of SARS-CoV-2, revealing its intricate structure in a unique and captivating way.
The sonification project, supported by MIT's Center for Art, Science and Technology (CAST) and the Mellon Foundation, transforms the spike protein's amino acid sequence, secondary structure patterns, and three-dimensional folds into a melodic composition. This innovative approach, a form of counterpoint music, presents notes played against notes, with the spike protein represented as interwoven melodies, forming a multi-layered composition.
AI plays a transformative role in protein design, using advanced deep learning and generative models to create functional proteins with specific binding properties more efficiently and accurately than traditional methods. These AI-designed proteins can be applied to develop non-toxic, sustainable materials, as well as to understand and target complex biological molecules like the spike protein of SARS-CoV-2.
Specific AI tools, such as RFdiffusion, ProteinMPNN, and Latent-X, generate protein structures that bind tightly and selectively to target molecules, even with limited input data like amino acid sequences. This approach enables the creation of high-affinity binding proteins useful for diagnostics, therapeutics, and biosensors, demonstrating robustness in real-world conditions.
In drug discovery and understanding protein behaviour, AI-driven tools like Microsoft's BioEmu model protein dynamics with near-experimental accuracy by simulating thousands of protein conformations rapidly. This helps elucidate functional structural changes, hidden binding pockets, and protein stability, enhancing rational drug design, including efforts targeting viral proteins such as SARS-CoV-2's spike protein.
The sonification of the spike protein can help scientists understand and design proteins, including potential mutations that may impact the virus's pathogenic power. In the longer term, the sonification of proteins could aid in drug design, particularly in the search for new proteins that match the melody and rhythm of an antibody capable of binding to the spike protein.
Moreover, the sonification of the spike protein can be used to compare its biochemical processes with those of previous coronaviruses like SARS or MERS. By understanding these differences, researchers can gain valuable insights into the evolution and behaviour of these viruses, which could inform future pandemic response and vaccine development efforts.
The use of AI in protein design and analysis accelerates the development of novel, non-toxic, and sustainable biomaterials by tailoring protein properties precisely and expediently. Co-authors of the studies in Extreme Mechanics Letters and APL Bioengineering hail from MIT, IBM Research, and Chi-Hua Yu, respectively. These advancements demonstrate the potential of AI to revolutionise our understanding and manipulation of proteins, with far-reaching implications for various fields, including medicine, materials science, and biology.
