Scientists have found new proteins that love to grab single‑strand DNA. They come from places like volcanic lakes in Iceland and deep‑sea vents far under the Atlantic Ocean.
Nature’s Hidden Toolbox
Many useful enzymes hide in nature, but we haven’t found them all yet. Researchers used modern DNA scanners to look through millions of gene sequences and spot the unusual ones.
These new proteins stick to DNA and stay strong even when the heat is high, the water is very acidic or salty, or the pressure is huge.
Why the Proteins Matter
Lab tests showed the proteins are very stable. They do not melt easily, which makes them good candidates for medical and industrial use.
Scientists also solved the 3‑D shapes of the proteins. Knowing the shape helps engineers improve them even more.
Making Fast Virus Tests Better
One of the proteins helped a test called LAMP work faster and catch more virus particles. LAMP can find the genetic material of germs without big machines.
When the protein was added, the test spotted the RNA of COVID‑19 and the DNA of other germs more quickly and at lower amounts.
Future Uses
Companies that make enzymes look for tools that can survive tough conditions. Proteins from hot springs or deep oceans are perfect because they already work there.
These discoveries also give artificial‑intelligence programs better examples to learn how proteins fold and how to design new ones.
What Comes Next
The team keeps searching for more DNA‑binding proteins. Some new ones may help create better LAMP tests for diseases like leishmaniasis and Chagas disease.
They are also working with a Norwegian biotech firm to turn the proteins into commercial products.
