In enzymology, chlorophyll synthase (EC 2.5.1.62) is an enzyme that catalyzes the chemical reaction
- chlorophyllide a + phytyl diphosphate chlorophyll a + diphosphate
The two substrates of this enzyme are chlorophyllide a and phytyl diphosphate; its two products are chlorophyll a and diphosphate. The same enzyme can act on chlorophyllide b to form chlorophyll b.
This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is chlorophyllide-a:phytyl-diphosphate phytyltransferase. This reaction is the final step of the complete biosynthetic pathway to chlorophylls from glutamic acid.[1][2]
