DE   3-vinylbacteriochlorophyllide d 3(1)-hydratase.
CA   a bacteriochlorophyllide d = a 3-vinylbacteriochlorophyllide d + H2O.
CC   -!- This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green
CC       flimentous bacteria (Chloroflexaceae), is involved in the
CC       biosynthesis of bacteriochlorophylls c, d and e.
CC   -!- It acts it the direction of hydration, and the hydroxyl group that is
CC       formed is essential for the ability of the resulting
CC       bacteriochlorophylls to self-aggregate in the chlorosomes, unique
CC       light-harvesting antenna structures found in these organisms.
