FunFam 13: Ferredoxin--NADP(+) reductase

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
Flavodoxin--NADP(+) reductase. [EC: 1.19.1.1]
Reduced flavodoxin + NADP(+) = oxidized flavodoxin + NADPH.
  • This activity occurs in some prokaryotes and algae that possess flavodoxin, and provides low-potential electrons for a variety of reactions such as nitrogen fixation, sulfur assimilation and amino acid biosynthesis.
  • In photosynthetic organisms it is involved in the photosynthetic electron transport chain.
  • The enzyme also catalyzes EC 1.18.1.2.

Ferredoxin--NADP(+) reductase. [EC: 1.18.1.2]
2 reduced ferredoxin + NADP(+) + H(+) = 2 oxidized ferredoxin + NADPH.
  • In chloroplasts and cyanobacteria the enzyme acts on plant-type [2Fe- 2S] ferredoxins, but in other bacteria it can also reduce bacterial 2[4Fe-4S] ferredoxins and flavodoxin.
  • Formerly EC 1.6.7.1 and EC 1.6.99.4.
