Enzyme Information
| 1.19.1.1 |
Flavodoxin--NADP(+) reductase.
based on mapping to UniProt P28861
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.

| 1.18.1.2 |
Ferredoxin--NADP(+) reductase.
based on mapping to UniProt P28861
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.
