Divinyl chlorophyllide a 8-vinyl-reductase

Template:Short description Template:Infobox enzyme In enzymology, divinyl chlorophyllide a 8-vinyl-reductase (EC 1.3.1.75) is an enzyme that catalyzes the chemical reaction

3,8-divinylprotochlorophyllide + NADPH + H⁺ $\rightleftharpoons$ protochlorophyllide + NADP⁺

The three substrates of this enzyme are 3,8-divinylprotochlorophyllide, NADPH, and H⁺; its two products are protochlorophyllide and NADP⁺. This enzyme can also convert alternative substrates, for example 3,8-divinyl chlorophyllide a and in all cases reduces a single specific vinyl group to an ethyl group.

This enzyme belongs to the family of oxidoreductases. The systematic name of this enzyme class is chlorophyllide-a :NADP+ oxidoreductase. Other names in common use include 3,8-divinyl protochlorophyllide a 8-vinyl-reductase, [4-vinyl]chlorophyllide a reductase, and 4VCR. This enzyme is part of the biosynthetic pathway to chlorophylls.
