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

parCDNA topoisomerase IV is essential for chromosome segregation. In an ATP-dependent manner, it acts to relax positive supercoils in DNA and performs the decatenation events required during the replication of a circular DNA molecule; DNA topoisomerase IV is composed of two subunits parC and parE; Belongs to the type-II topoisomerase family, type-IIA subfamily; Localized in the cytoplasm; High confidence in function and specificity. (911 aa)    
Predicted Functional Partners:
parE
DNA topoisomerase IV, subunit B; DNA topoisomerase IV is essential for chromosome segregation. In an ATP-dependent manner, It acts to relax positive supercoils in DNA and performs the decatenation events required during the replication of a circular DNA molecule; DNA topoisomerase IV is composed of two subunits parC and parE; Belongs to the type-II topoisomerase family, type-IIA subfamily; Localized in the cytoplasm; High confidence in function and specificity.
 
 0.996
gyrB
DNA gyrase, subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
 
 0.977
secD
Protein-export membrane protein secD; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. SecDF uses the proton motive force (PMF) to complete protein translocation after the ATP-dependent function of SecA; Belongs to the SecD/SecF family. SecD subfamily.
 
  
 0.795
argS
Arginyl-tRNA synthetase also called Arginine-tRNA ligase is a monomeric enzyme that catalyzes the transfer of arginine to specific tRNA molecule as the first step in protein biosynthesis; Belongs to the class-I aminoacyl-tRNA synthetase family; Localized in the cytoplasm; High confidence in function and specificity.
 
  
 0.693
metG
Methionyl-tRNA synthetase, class Ia; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
  
  
 0.675
nusA
Transcription termination factor NusA; Participates in both transcription termination and antitermination.
 
  
 0.649
rpoA
DNA-dependent RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
  
 0.605
pheT
Phenylalanyl-tRNA synthetase catalyzes the attachment of phenylalanyl to its cognate transfer RNA molecule in a highly specific two-step reaction. It is an alpha2/beta2 tetramer composed of 2 subunits that belongs to class II aminoacyl-tRNA synthetases. PheT codes the beta subunit and folds as an anti-parallel beta-sheet flanked by alpha-helices. Phenylalanyl-tRNA synthetase binds 2 magnesium ions per tetramer. Localized in the cytoplasm; High confidence in function and specificity.
  
  
 0.513
rpsA
Ribosomal protein S1; Binds mRNA; thus facilitating recognition of the initiation point. It is needed to translate mRNA with a short Shine-Dalgarno (SD) purine-rich sequence.
 
  
 0.507
dnaK
Molecular chaperone DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
 
 
 
 0.487
