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.

Score
napAPeriplasmic nitrate reductase; 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:
napB
Diheme cytochrome C protein; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
NapAB assembly 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.
 
 
 0.999
napC
Cytochrome C-type protein; Similar to Escherichia coli, Escherichia coli O6, and Escherichia coli O157:H7 cytochrome C-type protein NapC or b2202 or c2739 or z3459 or ecs3091 SWALL:NAPC_ECOLI (SWALL:P33932) (200 aa) fasta scores: E(): 3.2e-61, 73.36% id in 199 aa.
 
 0.996
napF
Ferredoxin-type protein; 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.
 
 
 0.995
nrfA
Cytochrome c552 precursor; Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
  
 
 0.987
napH
Similar to Escherichia coli ferredoxin-type protein NapH or b2204 SWALL:NAPH_ECOLI (SWALL:P33934) (287 aa) fasta scores: E(): 7.7e-90, 75.61% id in 287 aa.
 
  
 0.986
napG
Ferredoxin-type protein; Similar to Escherichia coli, Escherichia coli O6, and Shigella flexneri ferredoxin-type protein NapG or b2205 or c2744 or sf2289 SWALL:NAPG_ECOLI (SWALL:P33936) (231 aa) fasta scores: E(): 2.3e-68, 75.65% id in 230 aa.
 
 0.986
nasB
Similar to Klebsiella pneumoniae nitrite reductase [NAD(P)H] large subunit NasB SWALL:NIRB_KLEPN (SWALL:Q06458) (957 aa) fasta scores: E(): 0, 70.89% id in 962 aa; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 
 0.982
nirB
Similar to Escherichia coli nitrite reductase [NAD(P)H] large subunit NirB or b3365 SWALL:NIRB_ECOLI (SWALL:P08201) (847 aa) fasta scores: E(): 0, 80.45% id in 844 aa; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.982
nirD
Nitrite reductase [NAD(P)H] small subunit; Similar to Escherichia coli, and Escherichia coli O157:H7 nitrite reductase [NAD(P)H] small subunit NirD or b3366 or z4727 or ecs4217 SWALL:NIRD_ECOLI (SWALL:P23675) (108 aa) fasta scores: E(): 1.9e-27, 63.2% id in 106 aa.
