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

napAHypothetical protein; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (828 aa)    
Predicted Functional Partners:
CKO_00572
Hypothetical protein; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
Hypothetical 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.
  
 
 0.997

 0.989
CKO_00571
Hypothetical protein; KEGG: eci:UTI89_C2482 3.3e-149 napH; ferredoxin-type protein K02574; COG: COG0348 Polyferredoxin; Psort location: CytoplasmicMembrane, score:10.00.
 
  
 0.984
CKO_01829
Hypothetical protein; KEGG: eci:UTI89_C2480 7.4e-33 napC; cytochrome c protein, subunit of nitrate reductase, periplasmic K02569; COG: COG3005 Nitrate/TMAO reductases, membrane-bound tetraheme cytochrome c subunit; Psort location: CytoplasmicMembrane, score:8.02.

 0.965
CKO_01293
Hypothetical protein; KEGG: eca:ECA2991 0. nasB; nitrite reductase [NAD(P)H] large subunit K00362; COG: COG2146 Ferredoxin subunits of nitrite reductase and ring-hydroxylating dioxygenases; Psort location: Cytoplasmic, score:9.26; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.948
CKO_04789
Hypothetical protein; KEGG: stm:STM3474 0. nirB; nitrite reductase, large subunit K00362; COG: COG1251 NAD(P)H-nitrite reductase; Psort location: Cytoplasmic, score:9.97; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.946
CKO_04790
Hypothetical protein; KEGG: sfl:SF3385 3.8e-52 nirD; nitrite reductase (NAD(P)H) subunit K00363; COG: COG2146 Ferredoxin subunits of nitrite reductase and ring-hydroxylating dioxygenases; Psort location: Cytoplasmic, score:9.97.
