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

topADNA topoisomerase 1; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...] (757 aa)    
Predicted Functional Partners:
recQ
ATP-dependent DNA helicase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
 0.999
leuS
Leucine--tRNA ligase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.993
nifJ
Pyruvate-flavodoxin oxidoreductase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
   0.991
ssb
Single-stranded DNA-binding protein 2; Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism.
  
 
 0.980
ssb-2
Single-stranded DNA-binding protein 1; Function of homologous gene experimentally demonstrated in an other organism; factor.
  
 
 0.980
gltB-2
Glutamate synthase, large subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
  
 0.972
rpoA
RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.887
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.
 
 0.886
rpoC
RNA polymerase, beta prime subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.861
recA
DNA strand exchange and recombination protein with protease and nuclease activity; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.
