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.

napAPeriplasmic nitrate reductase subunit NapA apoprotein; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (831 aa)    
Predicted Functional Partners:
napB
Periplasmic nitrate reductase subunit NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
Periplasmic nitrate reductase chaperone NapD; Chaperone for NapA, the catalytic subunit of the periplasmic nitrate reductase. It binds directly and specifically to the twin- arginine signal peptide of NapA, preventing premature interaction with the Tat translocase and premature export.
 
 
 0.994
napC
Periplasmic nitrate reductase subunit NapC; PFAM: NapC/NirT cytochrome c domain protein; KEGG: vfi:VF1903 cytochrome c-type protein NapC.
 
 
 0.992
Ping_1024
TIGRFAM: nitrite reductase [NAD(P)H], large subunit; PFAM: FAD-dependent pyridine nucleotide-disulphide oxidoreductase; nitrite/sulfite reductase, hemoprotein beta-component, ferrodoxin domain protein; nitrite and sulphite reductase 4Fe-4S region; BFD domain protein [2Fe-2S]-binding domain protein; KEGG: ppr:PBPRA2523 putative NAD(P)H-nitrite reductase, large subunit.
 
 0.964
Ping_1023
TIGRFAM: nitrite reductase [NAD(P)H], small subunit; KEGG: ppr:PBPRA2522 putative nitrite reductase NADPH.
 
 
 0.941
Ping_1216
Hydrogen dehydrogenase; PFAM: ferredoxin; NADH ubiquinone oxidoreductase, 20 kDa subunit; KEGG: mca:MCA2725 NAD-reducing hydrogenase, gamma subunit.
 
  
 
 0.940
napF
Periplasmic nitrate reductase maturation protein NapF; Could be involved in the maturation of NapA, the catalytic subunit of the periplasmic nitrate reductase, before its export into the periplasm; Belongs to the NapF family.
 
  
 0.940
Ping_1026
PFAM: molybdopterin oxidoreductase; molydopterin dinucleotide-binding region; molybdopterin oxidoreductase Fe4S4 region; BFD domain protein [2Fe-2S]-binding domain protein; KEGG: ppr:PBPRA2525 hypothetical nitrate reductase large subunit; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. NasA/NapA/NarB subfamily.
  
  
0.938
Ping_1217
NAD(P)-dependent nickel-iron dehydrogenase flavin-containing subunit; PFAM: Respiratory-chain NADH dehydrogenase domain, 51 kDa subunit; KEGG: mca:MCA2724 NAD-reducing hydrogenase, alpha subunit.
  
 
 0.930
Ping_1022
TIGRFAM: nitrite transporter; PFAM: major facilitator superfamily MFS_1; KEGG: ppr:PBPRA2521 hypothetical nitrate transporter.
