Comment The enzyme, together with EC
1.1.1.396 , bacteriochlorophyllide-a dehydrogenase, and EC
4.2.1.165 , chlorophyllide-a 31-hydratase, is involved in the conversion of chlorophyllide a to bacteriochlorophyllide a. These enzymes can act in multiple orders, resulting in the formation of different intermediates, but the final product of the cumulative action of the three enzymes is always bacteriochlorophyllide a. This enzyme catalyses a trans-reduction of the B-ring; the product has the (7R,8R)-configuration. In addition, the enzyme has a latent activity of EC
1.3.7.13 , 3,8-divinyl protochlorophyllide a 8-vinyl-reductase (ferredoxin) [4]. The enzyme contains a [4Fe-4S] cluster, and structurally resembles the Fe protein/MoFe protein complex of nitrogenase (EC
1.18.6.1 ), which catalyses an ATP-driven reduction.
History EC 1.3.7.15 created 1965 as EC 1.3.99.35, modified 2012, transferred 2016 to EC 1.3.7.15
