Unveiling Two Billion Years of Nitrogenase Evolution Through Isotope Signatures

Understanding Nitrogen Isotope Fractionation

Recent studies highlight the significance of nitrogen isotope fractionation in sedimentary rocks. This phenomenon provides compelling evidence for biological nitrogen fixation and underscores early Earth’s primary productivity. Researchers have engineered nitrogenase evolution over a staggering two billion years, revealing persistent isotopic signatures.

Nitrogenase Isotope Signatures

This remarkable evolution of nitrogenase not only showcases the adaptability of life forms but also sheds light on the intricate biochemical processes that have shaped our planet. The findings promise to enhance our understanding of the role of nitrogen in Earth’s early biosphere and its ongoing impact on modern ecosystems.
