The nitrogenase cofactor biogenesis enzyme NifB is essential for the viability of methanogens

Jasleen Saini, Ahmed E. Dhamad, Abaranjitha Muniyasamy…·Daniel J. Lessner

This paper shows that NifB is essential for methanogen viability and functions beyond nitrogenase maturation, linking it to nitrogen fixation and methanogenesis.
