Protochlorophyllide reductase

In enzymology, a protochlorophyllide reductase (EC number|1.3.1.33) is an enzyme that catalyzes the chemical reaction

:chlorophyllide a + NADP⁺ $ightleftharpoons$ protochlorophyllide + NADPH + H⁺

Thus, the two substrates of this enzyme are chlorophyllide a and NADP⁺, whereas its 3 products are protochlorophyllide, NADPH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is chlorophyllide-a:NADP+ 7,8-oxidoreductase. Other names in common use include NADPH2-protochlorophyllide oxidoreductase, NADPH-protochlorophyllide oxidoreductase, NADPH-protochlorophyllide reductase, protochlorophyllide oxidoreductase, and protochlorophyllide photooxidoreductase. This enzyme participates in porphyrin and chlorophyll metabolism.
