STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nirCPutative nitrite transporter; 76% For/Nit_transpt. Pfam: PF01226; Form_Nir_trans; 1. In E. coli, NirC is a putative nitrite transporter which is a member of the FNT family of formate and nitrite transporters. The nirC gene is located in the nir operon which codes for a NADH-dependent nitrite reductase. NirC may function to import nitrite as a substrate for this enzyme complex. The nir operon is anaerobically expressed and is repressed by oxygen. TMhelix:6; High confidence in function and specificity. (270 aa)

nirD
Nitrite reductase [NAD(P)H] small subunit (EC 1.7.1.4). REQUIRED FOR ACTIVITY OF THE REDUCTASE. 66% simialr to the nirD protein from R. solanacearum,a probable nitrite reductase NADPH (small subunit) oxidoreductase protein [EC:1.7.1.4]. TREMBL:Q8XQK3. InterPro: Rieske iron-sulfur protein 2Fe-2S subunit In E.coli, the NADH-dependent nitrite reductase catalyzes the six-electron reduction of nitrite to ammonia and also catalyzes the two-electron reduction of hydroxylamine to ammonia. The enzyme is a FAD-flavoprotein, and also contains a siroheme and one 2Fe-2S center; Conserved hypothetic [...]
