Enzyme Information

1.3.7.7
Ferredoxin:protochlorophyllide reductase (ATP-dependent).
based on mapping to UniProt Q9F715
Protochlorophyllide a + reduced ferredoxin + 2 ATP + 2 H(2)O = chlorophyllide a + oxidized ferredoxin + 2 ADP + 2 phosphate.
-!- Occurs in photosynthetic bacteria, cyanobacteria, green algae and gymnosperms. -!- The enzyme catalyzes trans-reduction of the D-ring of protochlorophyllide; the product has the (7S,8S)-configuration. -!- Unlike EC 1.3.1.33 light is not required. -!- The enzyme contains a [4Fe-4S] cluster, and structurally resembles the Fe protein/MoFe protein complex of EC 1.18.6.1, which catalyzes an ATP-driven reduction.
