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

parCTopoisomerase-4 subunit A; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily. (740 aa)    
Predicted Functional Partners:
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.

parE
Topoisomerase-4 subunit B; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase family. ParE type 1 subfamily.

SDH51151.1
Hypothetical protein.
   
 
 0.891
yacG
Hypothetical protein; Inhibits all the catalytic activities of DNA gyrase by preventing its interaction with DNA. Acts by binding directly to the C- terminal domain of GyrB, which probably disrupts DNA binding by the gyrase.
    
 
 0.762
nusA
N utilization substance protein A; Participates in both transcription termination and antitermination.
 
  
 0.707
recO
DNA replication and repair protein RecO; Involved in DNA repair and RecF pathway recombination.
 
  
 0.692
SDG97284.1
Signal peptidase I; Belongs to the peptidase S26 family.
 
  
 0.688
pheT
phenylalanyl-tRNA synthetase beta chain; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.601
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. MetG type 2B subfamily.
  
  
 0.562
pheS
phenylalanyl-tRNA synthetase alpha chain; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily.
