Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...
