EC 1.3.7.13 Details

show Brenda entry

EC number

1.3.7.13

Accepted name

3,8-divinyl protochlorophyllide a 8-vinyl-reductase (ferredoxin)

Reaction

protochlorophyllide a + 2 oxidized ferredoxin [iron-sulfur] cluster = 3,8-divinyl protochlorophyllide a + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H⁺

Other name(s)

bciB (gene name), cyano-type divinyl chlorophyllide a 8-vinyl-reductase

Systematic name

protochlorophyllide-a:ferredoxin C-8¹-oxidoreductase

Comment

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).
