    Functioni

    Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (ChlN-ChlB) is the catalytic component of the complex.UniRule annotation

    Catalytic activityi

    Protochlorophyllide a + reduced ferredoxin + 2 ATP + 2 H2O = chlorophyllide a + oxidized ferredoxin + 2 ADP + 2 phosphate.UniRule annotation

    Cofactori

    Binds 1 [4Fe-4S] cluster per heterodimer. The cluster is bound at the heterodimer interface by residues from both subunits.UniRule annotation
