KEGG   ENZYME: 1.3.7.14Help
Entry
EC 1.3.7.14                 Enzyme                                 

Name
3,8-divinyl chlorophyllide a reductase
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With an iron-sulfur protein as acceptor
BRITE hierarchy
Sysname
bacteriochlorophyllide-g:ferredoxin C-81-oxidoreductase
Reaction(IUBMB)
bacteriochlorophyllide g + 2 oxidized ferredoxin [iron-sulfur] cluster + ADP + phosphate = 3,8-divinyl chlorophyllide a + 2 reduced ferredoxin [iron-sulfur] cluster + ATP + H2O + 2 H+ [RN:R11531]
Reaction(KEGG)
Substrate
bacteriochlorophyllide g [CPD:C21441];
oxidized ferredoxin [iron-sulfur] cluster [CPD:C00139];
ADP [CPD:C00008];
phosphate [CPD:C00009]
Product
3,8-divinyl chlorophyllide a [CPD:C11832];
reduced ferredoxin [iron-sulfur] cluster [CPD:C00138];
ATP [CPD:C00002];
H2O [CPD:C00001];
H+ [CPD:C00080]
Comment
The enzyme, found only in bacteriochlorophyll b-producing bacteria, catalyses the introduction of a C-8 ethylidene group. The enzyme contains a [4Fe-4S] cluster, and structurally resembles the Fe protein/MoFe protein complex of nitrogenase. It is very similar to EC 1.3.7.15, chlorophyllide a reductase, and is composed of three subunits. Two of them form the catalytic component, while the third one functions as an ATP-dependent reductase component that catalyses the electron transfer from ferredoxin to the catalytic component.
