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 L component
CC       serves as a unique electron donor to the NB-component of the
CC       complex, and binds Mg-ATP. {ECO:0000256|HAMAP-Rule:MF_00355}.
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_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-
CC       Rule:MF_00355}.
CC   -!- SUBUNIT: Homodimer. Protochlorophyllide reductase is composed of
CC       three subunits; ChlL, ChlN and ChlB. {ECO:0000256|HAMAP-
CC       Rule:MF_00355}.
CC   -!- SIMILARITY: Belongs to the NifH/BchL/ChlL family.
CC       {ECO:0000256|HAMAP-Rule:MF_00355, ECO:0000256|RuleBase:RU003688}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation
CC       of feature annotation. {ECO:0000256|HAMAP-Rule:MF_00355}.
