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 L component serves as a unique
CC electron donor to the NB-component of the complex, and binds Mg-ATP.
CC {ECO:0000256|HAMAP-Rule:MF_00355}.
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:83348, ChEBI:CHEBI:83350, ChEBI:CHEBI:456216; EC=1.3.7.7;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00355};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00355};
CC Note=Binds 1 [4Fe-4S] cluster per dimer. {ECO:0000256|HAMAP-
CC Rule:MF_00355};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; chlorophyll
CC biosynthesis (light-independent). {ECO:0000256|HAMAP-Rule:MF_00355}.
CC -!- SUBUNIT: Homodimer. Protochlorophyllide reductase is composed of three
CC subunits; ChlL, ChlN and ChlB. {ECO:0000256|HAMAP-Rule:MF_00355}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP-
CC Rule:MF_00355}.
CC -!- SIMILARITY: Belongs to the NifH/BchL/ChlL family.
CC {ECO:0000256|ARBA:ARBA00005504, ECO:0000256|HAMAP-Rule:MF_00355,
CC ECO:0000256|RuleBase:RU003688}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00355}.
