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

narKProbable nitrate transporters are involved in excretion of nitrite produced by the dissimilatory reduction of nitrate. NarK is polytopic membrane protein with 12 transmembrane domains which is involved in nitrate uptake and nitrite excretion and is thought to function as a nitrate/nitrite antiporter. At low concentrations of nitrate, NarK mediates the electrogenic excretion of nitrite rather than nitrate/nitrite exchange., 90% similarity to a probable nitrate transporter protein in Azoarcus sp. EbN1., InterPRo:04737: nitrate transporter,Signal peptide no present, TMHx:12, ; High confid [...] (404 aa)    
Predicted Functional Partners:
nasA
Probable Nitrate reductase. Homology to nasA of K. oxytoca of 41% (sprot|NASA_KLEOX). Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants fungi and bacteria. InterPro: Prokaryotic molybdopterin oxidoreductases (IPR006655) Pfam: Molybdopterin oxidoreductase; Molydopterin dinucleotide binding domain no signal peptide no TMH Helixturnhelix motif; High confidence in function and specificity; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.

nasC
Putative nitrate reducatse small subunit. Homology to nasC of K. oxytoca of 38% (trembl|Q48467). NasC probably mediates electron transfer from NADH to NasA, the nitrate reductase. InterPro: FAD-dependent pyridine nucleotide-disulphide oxidoreductase (IPR001327) Pfam: Pyridine nucleotide-disulfide oxidoreductase no signal peptide no TMHs; Family membership.

camA
Probable putidaredoxin reductase (EC 1.18.1.-). Homology to camA of P. putida of 48% (sprot|CAMA_PSEPU). The oxidation of camphor by cytochrome p450-cam requires the participation of a flavoprotein, putidaredoxin reductase, and an iron-sulfur protein, putidaredoxin, to mediate the transfer of electrons from nadh to p450 for oxygen activation. Interpro: FAD-dependent pyridine nucleotide-disulphide oxidoreductase (IRP001327), NAD binding site (IPR000205) Pfam: Pyridine nucleotide-disulphide oxidoreductase no signal peptide no TMHs; Family membership.
