ID 1.3.7.15 DE chlorophyllide a reductase. CA (1) 3-deacetyl-3-vinylbacteriochlorophyllide a + ADP + 2 oxidized [2Fe- CA 2S]-[ferredoxin] + phosphate = ATP + chlorophyllide a + H(+) + H2O + CA 2 reduced [2Fe-2S]-[ferredoxin]. CA (2) ADP + bacteriochlorophyllide a + 2 oxidized [2Fe-2S]-[ferredoxin] + CA phosphate = 3-acetyl-3-devinylchlorophyllide a + ATP + H(+) + H2O + CA 2 reduced [2Fe-2S]-[ferredoxin]. CA (3) 3-deacetyl-3-(1-hydroxyethyl)bacteriochlorophyllide a + ADP + CA 2 oxidized [2Fe-2S]-[ferredoxin] + phosphate = 3-devinyl-3- CA (1-hydroxyethyl)chlorophyllide a + ATP + H(+) + H2O + 2 reduced [2Fe-2S]- CA [ferredoxin]. CC -!- The enzyme, together with EC 1.1.1.396 and EC 4.2.1.165, is involved CC in the conversion of chlorophyllide a to bacteriochlorophyllide a. CC -!- These enzymes can act in multiple orders, resulting in the formation CC of different intermediates, but the final product of the cumulative CC action of the three enzymes is always bacteriochlorophyllide a. CC -!- This enzyme catalyzes a trans-reduction of the B-ring; the product CC has the (7R,8R)-configuration. CC -!- In addition, the enzyme has a latent activity of EC 1.3.7.13. CC -!- Formerly EC 1.3.99.35.
