Divinyl chlorophyllide a 8-vinyl-reductase

In enzymology, divinyl chlorophyllide "a" 8-vinyl-reductase () is an enzyme that catalyzes the chemical reaction
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.
