FunFam 29047: Light-independent protochlorophyllide reductase su...

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Ferredoxin:protochlorophyllide reductase (ATP-dependent). [EC: 1.3.7.7]
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.

Protochlorophyllide reductase. [EC: 1.3.1.33]
Chlorophyllide a + NADP(+) = protochlorophyllide + NADPH.
  • Catalyzes a light-dependent trans-reduction of the D-ring of protochlorophyllide; the product has the (7S,8S)-configuration.
