Comments

FUNCTION: Transports electrons between flavodoxin or ferredoxin and NADPH. Involved in the reductive activation of cobalamin-independent methionine synthase, pyruvate formate lyase and anaerobic ribonucleotide reductase. Also protects against superoxide radicals due to methyl viologen in the presence of oxygen.
CATALYTIC ACTIVITY: 2 reduced ferredoxin + NADP⁺ + H⁺ = 2 oxidized ferredoxin + NADPH.
COFACTOR: FAD.
SUBUNIT: Monomer.
SIMILARITY: Belongs to the ferredoxin--NADP reductase family.
SIMILARITY: Contains 1 FAD-binding FR-type domain.
CAUTION: Ref.6 authors incorrectly assigned the protein to be part of FPR, the C-terminal of glpX.
SEQUENCE CAUTION:
- Sequence=Z11767; Type=Frameshift; Positions=94, 127;
