CC   -!- FUNCTION: Catalyzes the stepwise hydrogenation of geranylgeraniol to
CC       phytol during bacteriochlorophyll A (BchlA) biosynthesis.
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3 NADP(+) + phytyl diphosphate = geranylgeranyl diphosphate +
CC         3 H(+) + 3 NADPH; Xref=Rhea:RHEA:26229, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:57533, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC         ChEBI:CHEBI:75434; EC=1.3.1.83;
CC   -!- PATHWAY: Porphyrin-containing compound metabolism; bacteriochlorophyll
CC       biosynthesis (light-independent).
CC   -!- SIMILARITY: Belongs to the geranylgeranyl reductase family. ChlP
CC       subfamily. {ECO:0000305}.
