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

zitBZinc transporter ZitB; Function of homologous gene experimentally demonstrated in an other organism; transporter. (325 aa)    
Predicted Functional Partners:
merP
Periplasmic mercury ion binding protein; Involved in mercury resistance. Acts as a mercury scavenger that specifically binds to a mercuric ion in the periplasm and probably passes it to the cytoplasmic mercuric reductase MerA via the mercuric transport protein MerT.
     
 0.811
merT
Mercury ion transport protein; Function of strongly homologous gene; transporter.
 
   
 0.787
cutA
Divalent-cation tolerance protein CutA; Function of homologous gene experimentally demonstrated in an other organism; factor.
     
 0.779
arsR
Arsenical resistance operon repressor; Function of homologous gene experimentally demonstrated in an other organism; regulator.
     
 0.749
metG
Methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family.
     
 0.608
copA
Copper-exporting ATPase; Function of strongly homologous gene; transporter.
  
  
 0.593
ftsH
Cell division protease FtsH; Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins; Belongs to the AAA ATPase family. In the central section; belongs to the AAA ATPase family.
  
    0.580
NIDE2928
Homologs of previously reported genes of unknown function.
       0.508
ubiE
Ubiquinone/menaquinone biosynthesis methyltransferase; Methyltransferase required for the conversion of demethylmenaquinol (DMKH2) to menaquinol (MKH2).
 
     0.439
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
  
 0.425
