light-independent protochlorophyllide reductase, N subunit
This enzyme describes the N subunit of the dark form protochlorophyllide reductase, a nitrogenase-like enzyme involved in bacteriochlorophyll biosynthesis. This subunit shows homology to the nitrogenase molybdenum-iron protein NifN. [Biosynthesis of cofactors, prosthetic groups, and carriers, Chlorophyll and bacteriochlorphyll]
