IntEnz Enzyme Nomenclature
EC 1.3.7.13

Names

Accepted name:
3,8-divinyl protochlorophyllide a 8-vinyl-reductase (ferredoxin)
Other names:
bciB (gene name)
cyano-type divinyl chlorophyllide a 8-vinyl-reductase
Systematic name:
protochlorophyllide-a:ferredoxin C-81-oxidoreductase

Reactions

Comments:

The enzyme, found in many phototrophic bacteria, land plants, and some green and red algae, is involved in the production of monovinyl versions of (bacterio)chlorophyll pigments from their divinyl precursors. Binds two [4Fe-4S] clusters and an FAD cofactor. It can also act on 3,8-divinyl chlorophyllide a, 3,8-divinyl chlorophyll a, and chlorophyll c2. cf. EC 1.3.1.75, 3,8-divinyl protochlorophyllide a 8-vinyl-reductase (NADPH).
