CC -!- FUNCTION: Component of the dark-operative protochlorophyllide reductase CC (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of CC protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This CC reaction is light-independent. The NB-protein (ChlN-ChlB) is the CC catalytic component of the complex. {ECO:0000256|ARBA:ARBA00025201, CC ECO:0000256|HAMAP-Rule:MF_00352}. CC -!- CATALYTIC ACTIVITY: CC Reaction=2 ADP + chlorophyllide a + oxidized 2[4Fe-4S]-[ferredoxin] + 2 CC phosphate = 2 ATP + 2 H2O + protochlorophyllide a + reduced 2[4Fe- CC 4S]-[ferredoxin]; Xref=Rhea:RHEA:28202, Rhea:RHEA-COMP:10002, CC Rhea:RHEA-COMP:10004, ChEBI:CHEBI:15377, ChEBI:CHEBI:30616, CC ChEBI:CHEBI:33722, ChEBI:CHEBI:33723, ChEBI:CHEBI:43474, CC ChEBI:CHEBI:83348, ChEBI:CHEBI:83350, ChEBI:CHEBI:456216; EC=1.3.7.7; CC Evidence={ECO:0000256|ARBA:ARBA00000802, ECO:0000256|HAMAP- CC 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 bound at CC 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|ARBA:ARBA00004949, CC ECO:0000256|HAMAP-Rule:MF_00352}. CC -!- SUBUNIT: Protochlorophyllide reductase is composed of three subunits; CC ChlL, ChlN and ChlB. Forms a heterotetramer of two ChlB and two ChlN CC subunits. {ECO:0000256|ARBA:ARBA00025959, ECO:0000256|HAMAP- CC Rule:MF_00352}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast CC {ECO:0000256|ARBA:ARBA00004229, ECO:0000256|HAMAP-Rule:MF_00352}. CC -!- SIMILARITY: Belongs to the BchN/ChlN family. {ECO:0000256|HAMAP- CC Rule:MF_00352}. CC -!- SIMILARITY: Belongs to the ChlB/BchB/BchZ family. CC {ECO:0000256|ARBA:ARBA00008935}.
