CC -!- FUNCTION: Component of the dark-operative protochlorophyllide CC reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce CC ring D of protochlorophyllide (Pchlide) to form chlorophyllide a CC (Chlide). This reaction is light-independent. The NB-protein CC (ChlN-ChlB) is the catalytic component of the complex. CC {ECO:0000256|HAMAP-Rule:MF_00352}. CC -!- CATALYTIC ACTIVITY: Protochlorophyllide a + reduced ferredoxin + 2 CC ATP + 2 H(2)O = chlorophyllide a + oxidized ferredoxin + 2 ADP + 2 CC phosphate. {ECO:0000256|HAMAP-Rule:MF_00352}. CC -!- COFACTOR: CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; CC Evidence={ECO:0000256|HAMAP-Rule:MF_00352}; CC Note=Binds 1 [4Fe-4S] cluster per heterodimer. The cluster is CC bound at the heterodimer interface by residues from both subunits. CC {ECO:0000256|HAMAP-Rule:MF_00352}; CC -!- PATHWAY: Porphyrin-containing compound metabolism; chlorophyll CC biosynthesis (light-independent). {ECO:0000256|HAMAP- CC Rule:MF_00352}. CC -!- SUBUNIT: Protochlorophyllide reductase is composed of three CC subunits; ChlL, ChlN and ChlB. Forms a heterotetramer of two ChlB CC and two ChlN subunits. {ECO:0000256|HAMAP-Rule:MF_00352}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP- CC Rule:MF_00352}. CC -!- SIMILARITY: Belongs to the BchN/ChlN family. {ECO:0000256|HAMAP- CC Rule:MF_00352}.
