Protein
Chlorophyll synthase, chloroplastic
Function
Involved in one of the last steps of the biosynthesis of chlorophyll a. Catalyzes the esterification of chlorophillide a with either geranylgeranyldiphosphate (GGPP) or phytyldiphosphate (PhyPP). May also use with a lower efficiency the monophosphates GGMP and PhyMP, but not the non-phosphorylated alcohols geranylgeraniol and phytol. The tetraprenyl diphosphate must bind to the enzyme as the first substrate and esterification occurs when this pre-loaded enzyme meets the second substrate, chlorophyllide.
Similarity
Belongs to the UbiA prenyltransferase family. Chlorophyll synthase subfamily.
