NCBI Protein Information
chlorophyll synthase
NCBI Summary
Encodes a protein with chlorophyll synthase activity. This enzyme has been shown to perform the esterification of chlorophyllide (a and b), the last step of chlorophyll biosynthesis. Although it can use either geranylgeranyl pyrophosphate (GGPP) or phytyl pyrophosphate (PhyPP) as substrates, the esterification reaction was faster with GGPP than with PhyPP.

UniProt Comments
Involved in one of the last steps of the biosynthesis of chlorophyll a. Catalyzes the esterification of chlorophillide a or b with a preference for geranylgeranyldiphosphate (GGPP) rather than for phytyldiphosphate (PhyPP).
