EC 1.3.1.75 Details

show Brenda entry

EC number

1.3.1.75

Accepted name

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

Reaction

protochlorophyllide a + NADP⁺ = 3,8-divinyl protochlorophyllide a + NADPH + H⁺

Other name(s)

DVR (gene name), bciA (gene name), [4-vinyl]chlorophyllide a reductase, 4VCR, chlorophyllide-a:NADP⁺ oxidoreductase, divinyl chlorophyllide a 8-vinyl-reductase, plant-type divinyl chlorophyllide a 8-vinyl-reductase

Systematic name

protochlorophyllide-a:NADP⁺ C-8¹-oxidoreductase

Comment

The enzyme, found in higher plants, green algae, and some phototrophic bacteria, is involved in the production of monovinyl versions of (bacterio)chlorophyll pigments from their divinyl precursors. It can also act on 3,8-divinyl chlorophyllide a. cf. EC 1.3.7.13, 3,8-divinyl protochlorophyllide a 8-vinyl-reductase (ferredoxin).
