The enzyme, together with EC 184.108.40.206, chlorophyllide-a reductase, and EC 220.127.116.116, bacteriochlorophyllide-a dehydrogenase, is involved in the conversion of chlorophyllide a to bacteriochlorophyllide a. The 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. The enzyme catalyses the hydration of a vinyl group on ring A, converting it to a hydroxyethyl group.
