In enzymology, chlorophyll synthase ({{EC number|2.5.1.62}}) is an enzyme that catalyzes the chemical reaction

:chlorophyllide a + phytyl diphosphate $\backslash rightleftharpoons$ 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 and similarly for chlorophyll d and f.{{cite journal | vauthors = Tsuzuki Y, Tsukatani Y, Yamakawa H, Itoh S, Fujita Y, Yamamoto H | title = Effects of Light and Oxygen on Chlorophyll d Biosynthesis in a Marine Cyanobacterium Acaryochloris marina | journal = Plants | volume = 11 | issue = 7 | pages = 915 | date = March 2022 | pmid = 35406896 | doi = 10.3390/plants11070915 | pmc = 9003380 | doi-access = free }}

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.{{cite journal | vauthors = Willows RD | title = Biosynthesis of chlorophylls from protoporphyrin IX | journal = Natural Product Reports | volume = 20 | issue = 3 | pages = 327–341 | date = June 2003 | pmid = 12828371 | doi = 10.1039/B110549N }}{{cite journal | vauthors = Bollivar DW | title = Recent advances in chlorophyll biosynthesis | journal = Photosynthesis Research | volume = 90 | issue = 2 | pages = 173–194 | date = November 2006 | pmid = 17370354 | doi = 10.1007/s11120-006-9076-6 | s2cid = 23808539 }}
