Comments
FUNCTION: Uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent (By similarity).

case not <OG:Chloroplast> and not <OC:Cyanobacteria>
PATHWAY: Porphyrin biosynthesis; bacteriochlorophyll biosynthesis (light-independent).
SUBUNIT: Protochlorophyllide reductase is thought to be composed of three subunits; bchL, bchN and bchB. Could form a heterotetramer of two bchB and two bchN subunits (By similarity).
end case


case <OC:Cyanobacteria>
PATHWAY: Porphyrin biosynthesis; chlorophyll biosynthesis (light-independent).
SUBUNIT: Protochlorophyllide reductase is thought to be composed of three subunits; chlL, chlN and chlB. Could form a heterotetramer of two chlB and two chlN subunits (By similarity).
end case


case <OG:Chloroplast>
PATHWAY: Porphyrin biosynthesis; chlorophyll biosynthesis (light-independent).
SUBUNIT: Protochlorophyllide reductase is thought to be composed of three subunits; chlL, chlN and chlB. Could form a heterotetramer of two chlB and two chlN subunits (By similarity).
SUBCELLULAR LOCATION: Plastid, chloroplast (By similarity).
end case

SIMILARITY: Belongs to the bchN/chlN family.
