Extreme Proteins from Volcanic Lakes and Deep-Sea Vents Enhance Rapid Disease Tests

Researchers have discovered robust DNA-binding proteins in extreme environments – including volcanic lakes in Iceland and deep-sea hydrothermal vents in the North Atlantic – that have the potential to significantly improve the speed and sensitivity of rapid diagnostic tests for infectious diseases. The findings, led by Durham University, could lead to better biotechnology tools and medical diagnostics.

Uncovering Nature’s Resilient Building Blocks

The international research team, with collaborators in Iceland, Norway and Poland, utilized next-generation DNA sequencing to scan vast genetic databases, identifying previously unknown proteins capable of remaining stable under harsh conditions such as high heat, salt, and extreme pH levels Durham University. These proteins, found in some of the most extreme places on Earth, exhibit exceptional durability and thermal stability, making them well-suited for applications in biotechnology, and medicine.

Boosting Diagnostic Accuracy with LAMP Technology

One of the newly discovered proteins demonstrated a significant enhancement in loop-mediated isothermal amplification (LAMP) diagnostic tests. LAMP tests detect genetic material from viruses, bacteria, or parasites without the need for complex laboratory equipment Durham University. The addition of the protein resulted in faster and more sensitive pathogen detection, including improved detection of SARS-CoV-2 viral RNA.

Implications for AI-Driven Protein Design

Professor Ehmke Pohl of Durham University highlighted the potential of bioprospecting in extreme habitats, stating the results are important for the bioeconomy and provide a foundation for Artificial Intelligence (AI) methods in protein structure prediction and protein design National Today. The structural information gained from these proteins can be used to refine them through protein design, and the diverse set of real biological examples benefits AI systems that model protein structures.

Future Research and Applications

Researchers are continuing to investigate additional DNA-binding proteins and are developing improved versions for apply in new LAMP tests targeting neglected tropical diseases like leishmaniasis and Chagas disease Durham University. Collaboration with the Norwegian biotechnology company ArcticZymes is underway to explore potential commercial applications for these newly discovered proteins.
