Heat-stable enzyme from deep-sea microbe turns nitrogen gas into ammonia

Scientists have discovered that a heat-stable enzyme from the deep-sea microbe Methanocaldococcus infernus can fix nitrogen at temperatures exceeding 90°C. This breakthrough provides insights into how biological nitrogen fixation can occur in extreme volcanic environments.
Why it matters
Understanding how enzymes function under extreme heat could lead to advancements in industrial biotechnology and sustainable agriculture.

Although nitrogen gas makes up around 78% of Earth's atmosphere, plants and animals cannot directly use it.
