EC Number
1.3.7.14
CAS Registry Number
Comments
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.
Cofactor
iron-sulfur
History
Reactions
Bacteriochlorophyllide g + 2 oxidized ferredoxin [iron-sulfur] cluster + Adp + phosphate = 3,8-divinyl chlorophyllide a + 2 reduced ferredoxin [iron-sulfur] cluster + Atp + H(2)O + 2 H(+).
