ENZYME entry: EC 1.3.7.15

Accepted Name
Chlorophyllide a reductase.
Reaction catalysed
  • 3-deacetyl-3-vinylbacteriochlorophyllide a + 2 oxidized ferredoxin [iron-sulfur] cluster + ADP + phosphate <=> chlorophyllide a + 2 reduced ferredoxin [iron-sulfur] cluster + ATP + H(2)O + 2 H(+)
  • Bacteriochlorophyllide a + 2 oxidized ferredoxin [iron-sulfur] cluster + ADP + phosphate <=> 3-acetyl-3-devinylchlorophyllide a + 2 reduced ferredoxin [iron-sulfur] cluster + ATP + H(2)O + 2 H(+)
  • 3-deacetyl-3-(1-hydroxyethyl)bacteriochlorophyllide a + 2 oxidized ferredoxin [iron-sulfur] cluster + ADP + phosphate <=> 3-devinyl-3-(1-hydroxyethyl)chlorophyllide a + 2 reduced ferredoxin [iron-sulfur] cluster + ATP + H(2)O + 2 H(+)
Cofactor(s)
Iron-sulfur.
Comment(s)
  • The enzyme, together with EC 1.1.1.396 and EC 4.2.1.165, is involved in the conversion of chlorophyllide a to bacteriochlorophyllide a.
  • These enzymes can act in multiple orders, resulting in the formation of different intermediates, but the final product of the cumulative action of the three enzymes is always bacteriochlorophyllide a.
  • This enzyme catalyzes a trans-reduction of the B-ring; the product has the (7R,8R)-configuration.
  • In addition, the enzyme has a latent activity of EC 1.3.7.13.
  • Formerly EC 1.3.99.35.
