Protein

Inducible nitrate reductase [NADH] 1

Gene

INR1

Organism
Glycine max (Soybean) (Glycine hispida)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria.

Catalytic activityi

Nitrite + NAD+ + H2O = nitrate + NADH.

Cofactori

Protein has several cofactor binding sites:
  • FADBy similarityNote: Binds 1 FAD.By similarity
  • hemeBy similarityNote: Binds 1 heme group. The heme group is called cytochrome b-557.By similarity
  • Mo-molybdopterinBy similarityNote: Binds 1 Mo-molybdopterin (Mo-MPT) cofactor per subunit.By similarity
