They discovered a new class of proteins that stabilize methane deposits

In a recent study, scientists have made a groundbreaking discovery, revealing a previously unknown class of proteins that play an important role in stabilizing methane deposits found in cage-like chemical structures on Earth. These structures, known as methane clathrates, are not exclusive to our planet and have been observed on celestial bodies within our solar system.

Under the direction of Jennifer Glass, a professor at the Georgia Institute of Technology, the research focuses on the stability of methane clathrates under high pressure conditions at sea. The team analyzed a sample recovered from the sea floor near the coast of Oregon, providing unprecedented insights into this mysterious phenomenon.

Methane clathrates, which resemble solid forms of ice, form when microorganisms in ocean waters convert organic materials into methane, which is trapped inside the cages. Eventually, these deposits turn into gas and rise to the surface. However, in regions such as the rapidly warming Arctic, large amounts of methane escape before they can be used by biological communities.

The study identified a class of proteins called bacterial clathrate-binding proteins (CbpAs), which interact directly with the clathrate structure, influencing its growth. These proteins have antifreeze properties, similar to those that help fish survive in cold temperatures. This discovery not only sheds light on the stability of methane clathrates, but also suggests possible implications for extraterrestrial environments.

The researchers suggest that similar proteins may play a role in stabilizing methane clathrates in celestial bodies such as Mars, Saturn’s moon Titan, and possibly even in the potentially habitable areas of Enceladus. , a moon of Saturn, and Europa, a moon of Jupiter.

These findings show an exciting prospect for the search for alien life, showing that if microbes exist on other worlds, they can use similar mechanisms to create and stabilize methane clathrates, which affect the composition of ocean waters and atmosphere. To unravel the mysteries of extraterrestrial life, investigating the presence of methane clathrates will be crucial.
