KEGG   ENZYME: 4.2.1.165
Entry
EC 4.2.1.165                Enzyme                                 
Name
chlorophyllide a 31-hydratase;
bchF (gene name)
Class
Lyases;
Carbon-oxygen lyases;
Hydro-lyases
Sysname
chlorophyllide-a 31-hydro-lyase
Reaction(IUBMB)
(1) 3-devinyl-3-(1-hydroxyethyl)chlorophyllide a = chlorophyllide a + H2O [RN:R09059];
(2) 3-deacetyl-3-(1-hydroxyethyl)bacteriochlorophyllide a = 3-deacetyl-3-vinylbacteriochlorophyllide a + H2O [RN:R09054]
Reaction(KEGG)
R09054 R09059
Substrate
3-devinyl-3-(1-hydroxyethyl)chlorophyllide a [CPD:C18154];
3-deacetyl-3-(1-hydroxyethyl)bacteriochlorophyllide a [CPD:C18153]
Product
chlorophyllide a [CPD:C02139];
H2O [CPD:C00001];
3-deacetyl-3-vinylbacteriochlorophyllide a [CPD:C18152]
Comment
The enzyme, together with EC 1.3.7.15, chlorophyllide-a reductase, and EC 1.1.1.396, 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.
