CC   -!- FUNCTION: Involved in the activation and reutilization of phytol from
CC       chlorophyll degradation in plant metabolism, including tocopherol
CC       biosynthesis. Catalyzes the conversion of phytol to phytol
CC       monophosphate (PMP) (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=CTP + phytol = CDP + H(+) + phytyl phosphate;
CC         Xref=Rhea:RHEA:38055, ChEBI:CHEBI:15378, ChEBI:CHEBI:17327,
CC         ChEBI:CHEBI:37563, ChEBI:CHEBI:58069, ChEBI:CHEBI:75483;
CC         EC=2.7.1.182;
CC   -!- PATHWAY: Cofactor biosynthesis; tocopherol biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast membrane {ECO:0000305};
CC       Multi-pass membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the polyprenol kinase family. {ECO:0000305}.
