EC 4.2.1.169 Details
show Brenda entryEC number
4.2.1.169
Accepted name
3-vinyl bacteriochlorophyllide d 31-hydratase
Reaction
a 3-(1-hydroxyethyl) bacteriochlorophyllide d = a 3-vinyl bacteriochlorophyllide d + H2O
Other name(s)
bchV (gene name)
Systematic name
3-vinylbacteriochlorophyllide-d 31-hydro-lyase
Comment
This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green flimentous bacteria (Chloroflexaceae), is involved in the biosynthesis of bacteriochlorophylls c, d and e. It acts in the direction of hydration, and the hydroxyl group that is formed is essential for the ability of the resulting bacteriochlorophylls to self-aggregate in the chlorosomes, unique light-harvesting antenna structures found in these organisms. The product is formed preferentially in the (R)-configuration.
