3,8-divinyl protochlorophyllide a [CPD:C11831];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
The enzyme, found in higher plants, green algae, and some phototrophic bacteria, is involved in the production of monovinyl versions of (bacterio)chlorophyll pigments from their divinyl precursors. It can also act on 3,8-divinyl chlorophyllide a. cf. EC 1.3.7.13, 3,8-divinyl protochlorophyllide a 8-vinyl-reductase (ferredoxin).
