In enzymology, a divinyl chlorophyllide a 8-vinyl-reductase ({{EC number|1.3.1.75}}) is an enzyme that catalyzes the chemical reaction

chlorophyllide a + NADP⁺ divinyl chlorophyllide a + NADPH + H⁺

Thus, the two substrates of this enzyme are chlorophyllide a and NADP⁺, whereas its 3 products are divinyl chlorophyllide a, 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+ oxidoreductase. Other names in common use include [4-vinyl]chlorophyllide a reductase, and 4VCR. This enzyme participates in porphyrin and chlorophyll metabolism.
