At the California Institute of Technology, a group of ambitious high school students gathered to participate in a prestigious competition known as the International Genetically Engineered Machine (iGEM). This platform is one of the world’s premier synthetic biology competitions that encourages young minds to solve critical global issues through innovative biological designs. Among the participants was a particularly driven team from Southern California, named the PFAS Annihilators, well known for their unique approach leveraging AI to design enzymes targeting the degradation of PFAS. Their journey began on a sunny Saturday morning when these students laid the groundwork for a project that would soon capture international attention. Engaging in collaborative discussions and spirited brainstorming sessions, they formulated a bold plan to use artificial intelligence as a tool in designing specific enzymes to dismantle the strong carbon-fluorine bonds inherent in PFAS.
The importance of addressing PFAS contamination cannot be overstated, as these chemicals have proven resistant to breakdown due to their carbon-fluorine bonds—the strongest single bonds in organic chemistry. Consequently, traditional methods of treating PFAS have often been fraught with difficulties and inconsistencies. Recognizing the unique capabilities of AI, the PFAS Annihilators embarked on an experimental path, investing considerable effort in training a large language model (LLM) to assist in the creation of specialized enzymes. The road ahead was uncharted, filled with both obstacles and opportunities, as students sought to advance their understanding and practical application of synthetic biology.
Developing the AI Model
The PFAS Annihilators faced numerous challenges, primarily centered around the need to develop an AI model capable of engineering enzyme candidates that could efficiently break down PFAS. Leveraging a large language model, the students aspired to create modifications of naturally occurring enzymes, enhancing their ability to degrade the resilient carbon-fluorine bonds in PFAS compounds. Their journey took an exciting turn upon the discovery of a natural enzyme named A6RdhA, which is produced by a soil bacterium and contains potential attributes useful in their quest. The process of tailoring this enzyme to effectively target PFAS, however, was anything but straightforward.
The students had to contend with the complexities of protein design, a task made more daunting by the incomplete protein sequence of their chosen enzyme. Undeterred, they turned to an extensive repository of protein sequence databases, generating thousands of potential sequences through computational modeling. From this enormous pool, they aimed to identify novel chimeric enzymes by creating hybrids of A6RdhA and structurally similar proteins. This phase of the project highlighted the intersection of computational biology, engineering, and creativity, as students ventured into uncharted territory to develop new molecular architectures capable of unbinding the “forever” nature of PFAS.

The endeavor to synthesize the newly designed enzymes in laboratory settings presented a series of formidable challenges for the team. Producing AI-designed proteins is often fraught with technical issues, as cellular systems may not readily recognize or properly fold foreign sequences. These limitations have historically stymied similar projects within the field of synthetic biology. In addressing this challenge, the PFAS Annihilators opted to utilize a specialized cell-free system, supplemented with specific cofactors necessary for successful enzyme expression. This approach allowed the team to circumvent some of the traditional pitfalls associated with cellular expression systems, all while maintaining focus on achieving operational enzymes in practical testing environments.
Their persistence eventually bore fruit, as they succeeded in synthesizing several iterations of their engineered enzymes. This achievement was particularly noteworthy given the myriad of obstacles faced in producing viable protein candidates designed and initially constructed via AI systems. Through meticulous attention to detail and an unwavering commitment to problem-solving, the PFAS Annihilators transformed theoretical concepts into tangible laboratory successes.
Intricacies of Enzyme Functionality
Enzyme functionality hinges on a delicate interplay of structural integrity and chemical activity, with even the smallest variations in sequence potentially yielding substantial changes in performance. As such, the process of fine-tuning their AI-designed enzymes involved comprehensive testing to assess stability, operational viability, and efficacy in PFAS degradation. This phase required extensive iterations and methodical experimentation to evaluate the enzymatic capabilities to address the PFAS challenge meaningfully.
The students embraced a systematic approach, employing iterative sampling and rigorous statistical models to derive insightful data from their lab experiments. The culmination of this phase was rooted in their ability to demonstrate real-world applicability, thereby reinforcing the foundational principles of sustainable chemical processes through enzymatic action.
