The Nif gene refers to a set of genes involved in nitrogen fixation, primarily found in certain bacteria and archaea. Nitrogen fixation is the process by which atmospheric nitrogen (N₂) is converted into a form that can be utilized by living organisms, primarily ammonia (NH₃). This process is critical for the synthesis of amino acids and nucleotides, which are essential for life.
