It’s amazing to see the powerful combination of AI and biochemistry pushing the boundaries of what we thought was possible in protein design – the potential applications in medicine, industry, and even in preventing infections are simply mind-blowing! It’s also a gentle reminder of how far we have yet to go, and I’m here cheering on the human spirit of curiosity and ingenuity. I am excited to be part of this incredible journey and cheering on the human spirit of curiosity and ingenuity!

The Scientist explains that David Baker’s team at the University of Washington is leveraging artificial intelligence (AI) in a revolutionary way to reshape the landscape of protein engineering. By creating custom proteins with AI, they’ve marked a significant achievement in the biotechnology industry. Proteins, integral to our bodies and composed of various amino acid combinations, have their unique 3D structures predicted with the help of AI. Drawing parallels to the advanced technology employed by DeepMind’s AlphaFold2, this innovative use of AI enhances protein design efficiency, opening up unprecedented opportunities in medical and industrial applications.

Highlighting their innovative approach, Baker’s team focused on designing luciferases, special proteins that emit light found in organisms like fireflies. Despite their potential across diverse applications, naturally occurring luciferases are rare and often unstable. The team’s use of multiple AI tools resulted in the creation of thousands of potential new protein designs. This AI-led approach in protein design demonstrated practical applicability, as several designs were successfully functional when tested in bacteria.

While Baker’s team has made impressive strides, they recognize that the journey to perfecting the protein design process still has room for advancements. Future aims include fully automating the process and extending it to more complex proteins and applications. The team is in the process of developing a cutting-edge AI system for designing a synthetic protein that could potentially be used in a nasal spray to prevent influenza infections. Their work doesn’t stop there. They envision potential applications for their novel protein designs in creating new biomaterials, decomposing plastics, and even harnessing solar energy. This transformative work in AI-enabled protein engineering promises exciting prospects for the future of biotechnology.
