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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

fieFFerrous-iron efflux pump FieF; Iron-efflux transporter responsible for iron detoxification. Also able to transport Zn(2+) in a proton- dependent manner; Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. FieF subfamily (300 aa)    
Predicted Functional Partners:
zntA
Zinc/cadmium/lead-transporting P-type ATPase; Confers resistance to zinc, cadmium and lead. Couples the hydrolysis of ATP with the export of zinc, cadmium or lead, with highest activity when the metals are present as metal-thiolate complexes. Can also bind nickel, copper, cobalt and mercury; Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily
  
  
 0.856
zupT
Zinc transporter ZupT; Mediates zinc uptake. May also transport other divalent cations such as copper and cadmium ions
 
  
 0.717
zntR
HTH-type transcriptional regulator ZntR; Zinc-responsive transcriptional regulator of zntA
     
 0.686
emrE
Multidrug transporter EmrE; Multidrug transporter that expels positively charged hydrophobic drugs across the inner membrane of E.coli., thereby conferring resistance to a wide range of toxic compounds. The drug efflux is coupled to an influx of protons. Is involved in the resistance of E.coli cells to methyl viologen, ethidium bromide and acriflavine. Is also able to transport tetraphenylphosphonium (TPP(+)) and benzalkonium; Belongs to the small multidrug resistance (SMR) protein family
     
 0.681
cpxP
Periplasmic protein CpxP; Acts as an auxiliary protein in the Cpx two-component envelope stress response system, helping modulate the Cpx response systems response to some inducers. Binds the periplasmic domain of sensor histidine kinase CpxA, inhibiting induction of the Cpx envelope stress response in the absence of inducer; overexpression decreases Cpx pathway activity. Some periplasmic stimulii (shown for P pili subunit PapE and probably 0.3 M NaCl) increase CpxP's susceptibility to DegP, leading to CpxP degradation, inducing the Cpx pathway. Aids in combating extracytoplasmic prote [...]
     
 0.602
rnd
Ribonuclease D; Exonuclease involved in the 3' processing of various precursor tRNAs. Initiates hydrolysis at the 3'-terminus of an RNA molecule and releases 5'-mononucleotides; Belongs to the RNase D family
  
  
 0.595
livF
High-affinity branched-chain amino acid transport ATP-binding protein LivF; Component of the leucine-specific transport system
      
 0.569
zraP
Zinc resistance-associated protein; Binds zinc. Could be an important component of the zinc- balancing mechanism
     
 0.564
pfkA
ATP-dependent 6-phosphofructokinase isozyme 1; Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis; Belongs to the phosphofructokinase type A (PFKA) family. ATP-dependent PFK group I subfamily. Prokaryotic clade "B1" sub-subfamily
  
    0.561
znuC
Zinc import ATP-binding protein ZnuC; Part of the ABC transporter complex ZnuABC involved in zinc import. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. Zinc importer (TC 3.A.1.15.5) family
