NAR1 — Fusarium oxysporum f. sp. lycopersici 4287

Summary

FOXG_16837 (symbol NAR1, also known as niaD) on chromosome 13 of Fusarium oxysporum f. sp. lycopersici 4287 encodes a protein with nitrate reductase (NADPH) activity, sulfite oxidase activity, and cytochrome-b5 reductase activity acting on NAD(P)H. The protein contains molybdopterin oxidoreductase, MoCF oxidoreductase dimer, and Ig E-set domains, and binds molybdenum, FAD, heme, and the molybdenum cofactor. NAR1 is associated with nitrate assimilation, anaerobic respiration, nitric oxide anabolism, sulfur metabolism, and invasive growth. Related genes in other species link the family to nitrate reductase (EC 1.7.1.3) activity.
