CC   -!- FUNCTION: Uses Mg-ATP and reduced ferredoxin to reduce ring D of
CC       protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide)
CC       (By similarity). This reaction is light-independent.
CC   -!- PATHWAY: Porphyrin biosynthesis; chlorophyll biosynthesis (light-
CC       independent).
CC   -!- SUBUNIT: Protochlorophyllide reductase is thought to be composed
CC       of three subunits; chlL, chlN and chlB. Could form a
CC       heterotetramer of two chlB and two chlN subunits (By similarity).
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the bchN/chlN family.
