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.

napB1Probable diheme cytochrome C; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family. (155 aa)    
Predicted Functional Partners:
napA1
Nitrate reductase; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
 
 0.992
napC1
Probable cytochrome c-type protein NapC. Homology to napC of r. sphaeroides of 67% (sprot|NAPC_RHOSH). MEDIATES ELECTRON FLOW FROM QUINONES TO THE NAPAB COMPLEX. signal peptide no TMHs; High confidence in function and specificity.
 
 
 0.989
napA2
Probable nitrate reductase; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite.
 
 0.968
napH
Probabe iron-sulfur 4Fe-4s ferredoxin transmembrane protein. Homology to napH of E. coli of 43% (sprot|NAPH_ECOLI) Involved in a membrane generated redox potential. InterPro: 4Fe-4S ferredoxin iron-sulfur binding domain (IPR001450) Pfam: 4Fe-4S binding domain no signal peptide 4 TMHs; High confidence in function and specificity.
 
  
 0.966
napC2
Probable cytochrome c-type protein NapC. Homology to napC of R. sphaeroides of 57% (sprot|NAPC_RHOSH). MEDIATES ELECTRON FLOW FROM QUINONES TO THE NAPAB COMPLEX. no signal peptide probable 1 TMHs; High confidence in function and specificity.
 
 
 0.960
napD1
Putative NapD protein; 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.
  
  
 0.935
napG
Probable ferredoxin-type protein napG. Homology to napG of E. coli of 57% (sprot|NAPG_ECOLI). Involved in electron transfer in a wide variety of metabolic reactions. InterPro: MauM/NapG family ferredoxin-type protein (IPR004494); 7 Fe ferredoxin (IPR000813); 4Fe-4S ferredoxin; iron-sulfur binding domain (IPR001450) Pfam: 4Fe-4S binding domain Tigrfam: mauM_napG: MauM/NapG family ferredoxin-type protein no signal peptide no TMHs; High confidence in function and specificity.
 
  
 0.925
napF
Probable ferredoxin-type 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.
 
  
 0.883
napE
Putative periplasmic nitrate reductase accessory protein NapE. Homology to napE of R. sphaeroides of 36% (trembl|O88159). Pfam: Periplasmic nitrate reductase protein NapE (PF06796) This family consists of several bacterial periplasmic nitrate reductase NapE proteins. NapE is thought to be a transmembrane protein of the reductase. Interpro: Periplasmic nitrate reductase protein NapE (IPR010649) no signal peptide 1 TMH; Family membership.
  
  
 0.815
napD2
Probable NapD protein; 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.
