Entry

Name
3-vinyl bacteriochlorophyllide d 31-hydratase;
bchV (gene name)
Class
Lyases;
Carbon-oxygen lyases;
Hydro-lyases
Sysname
3-vinylbacteriochlorophyllide-d 31-hydro-lyase
Reaction(IUBMB)
a 3-(1-hydroxyethyl) bacteriochlorophyllide d = a 3-vinyl bacteriochlorophyllide d + H2O [RN:R11506]
Reaction(KEGG)
Substrate
3-(1-hydroxyethyl) bacteriochlorophyllide d
Product
3-vinyl bacteriochlorophyllide d [CPD:C21426];
H2O [CPD:C00001]
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.
