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

arsBArsenite/antimonite transporter; Involved in arsenical resistance. Thought to form the channel of an arsenite pump (By similarity); Belongs to the ArsB family. (429 aa)    
Predicted Functional Partners:
arsR
Arsenical resistance operon transcriptional repressor; Transcriptional repressor for the arsEFG operon. ArsE is a trans-acting regulatory protein which controls its own expression. The repressive effect of ArsE is alleviated by oxyions of +III oxidation state of arsenic, antimony, and bismuth, as well as arsenate (As(V)) (By similarity).
  
 0.996
arsC
Arsenate reductase; Reduction of arsenate [As(V)] to arsenite [As(III)]. This protein expands the substrate specificity of ArsAB pump which can extrude arsenite and antimonite to allow for arsenate pumping and resistance (By similarity); Belongs to the ArsC family.
  
  
 0.979
cusS
Copper-sensing histidine kinase in two-component regulatory system with CusR; Member of the two-component regulatory system CusS/CusR involved in response to copper and silver. Acts as a copper/silver ion sensor. Activates CusR by phosphorylation.
      
 0.600
cusF
Periplasmic copper- and silver-binding protein; Part of a cation efflux system that mediates resistance to copper and silver. Binds one copper per polypeptide.
  
   
 0.589
cusA
Copper/silver efflux system, membrane component; Part of a cation efflux system that mediates resistance to copper and silver; Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
      
 0.555
cusR
Response regulator in two-component regulatory system with CusS; Member of the two-component regulatory system CusS/CusR involved in response to copper and silver. Activates the expression of cusCFBA, hiuH and plasmid pRJ1004 gene pcoE in response to increasing levels of copper or silver ions. Can also increase the basal-level expression of copper resistance gene operon pcoABCD.
      
 0.530
cusC
Copper/silver efflux system, outer membrane component; Forms pores that allow passive diffusion of cations across the outer membrane. Part of a cation efflux system that mediates resistance to copper and silver. In pathogenic strains it allows the bacteria to invade brain microvascular endothelial cells (BMEC) thus allowing it to cross the blood-brain barrier and cause neonatal meningitis.
      
 0.529
cusB
Copper/silver efflux system, membrane fusion protein; Part of a cation efflux system that mediates resistance to copper and silver.
      
 0.521
cueR
Copper-responsive regulon transcriptional regulator; Regulates the transcription of the copA and cueO genes. It detects cytoplasmic copper stress and activates transcription in response to increasing copper concentrations.
      
 0.487
sugE
Multidrug efflux system protein; Guanidinium ion exporter. Couples guanidinium export to the proton motive force, exchanging one guanidinium ion for two protons. Overexpression leads to resistance to a subset of toxic quaternary ammonium compounds such as cetylpyridinium, cetyldimethylethyl ammonium and cetrimide cations. Belongs to the drug/metabolite transporter (DMT) superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family. Gdx/SugE subfamily.
