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

Score
napAPeriplasmic nitrate reductase precursor; Catalytic subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from NapB and catalyzes the reduction of nitrate to nitrite. (830 aa)    
Predicted Functional Partners:
napB
Cytochrome C-type protein NapB precursor; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
 0.999
napD
Conserved 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.
 
 
 0.999
napC
Similar to Escherichia coli cytochrome C-type protein NapC SW:NAPC_ECOLI (P33932) (200 aa) fasta scores: E(): 0, 75.5% id in 200 aa, and to Haemophilus influenzae cytochrome C-type protein NapC or hi0348 SW:NAPC_HAEIN (P44655) (200 aa) fasta scores: E(): 0, 61.8% id in 199 aa.
 
 0.996
napF
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.
 
 
 0.996
nirB
Nitrite reductase; Similar to Escherichia coli nitrite reductase NirB SW:NIRB_ECOLI (P08201) (847 aa) fasta scores: E(): 0, 82.7% id in 849 aa; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 0.969
fdoI
Similar to Escherichia coli formate dehydrogenase,cytochrome b556 protein FdoI SW:FDOI_ECOLI (P32174) (211 aa) fasta scores: E(): 0, 79.5% id in 210 aa, and to Haemophilus influenzae formate dehydrogenase, cytochrome b556 protein FdxI SW:FDXI_HAEIN (P44451) (238 aa) fasta scores: E(): 0, 50.0% id in 202 aa.
  
 0.966
nirD
Nitrite reductase [NAD; Similar to Escherichia coli nitrite reductase NirD SW:NIRD_ECOLI (P23675) (108 aa) fasta scores: E(): 1.6e-32,69.8% id in 106 aa.
 
 
 0.962
dmsB
Similar to Escherichia coli anaerobic dimethyl sulfoxide reductase chain B protein DmsB SW:DMSB_ECOLI (P18776) (204 aa) fasta scores: E(): 0, 61.1% id in 203 aa,and to Yersinia pestis probable dimethyl sulfoxide reductase subunit B protein DmsB TR:Q9X6B5 (EMBL:AF135170) (205 aa) fasta scores: E(): 0, 63.5% id in 203 aa. Similar to YPO3324 (63.5% identity in 203 aa overlap).
