ID   1.3.7.14
DE   3,8-divinyl chlorophyllide a reductase.
CA   ADP + bacteriochlorophyllide g + 2 oxidized [2Fe-2S]-[ferredoxin] +
CA   phosphate = 3,8-divinyl chlorophyllide a + ATP + H(+) + H2O + 2 reduced
CA   [2Fe-2S]-[ferredoxin].
CC   -!- The enzyme, found only in bacteriochlorophyll b-producing bacteria,
CC       catalyzes the introduction of a C-8 ethylidene group.
CC   -!- The enzyme contains a [4Fe-4S] cluster, and structurally resembles
CC       the Fe protein/MoFe protein complex of nitrogenase.
CC   -!- It is very similar to EC 1.3.7.15 and is composed of three subunits.
CC   -!- Two of them form the catalytic component, while the third one
CC       functions as an ATP-dependent reductase component that catalyzes the
CC       electron transfer from ferredoxin to the catalytic component.
