Brassica napus (Rape)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
