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 I (omega protein) (relaxing enzyme) (untwisting enzyme) (swivelase); 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 un [...] (866 aa)    
Predicted Functional Partners:
gltB
Glutamate synthase [NADPH] large chain precursor (glutamate synthase alpha subunit) (NADPH-GOGAT) (GLTS alpha chain).
  
  
 0.902
plu1039
Unnamed protein product; Highly similar to single-stranded DNA-binding protein SSB.
  
 
 0.899
ssb
Single-strand binding protein (SSB) (helix-destabilizing protein); 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.
  
 
 0.899
plu4452
Unnamed protein product; Similar to ATP-dependent DNA helicase.
  
 0.896
leuS
leucine-tRNA synthetase (leucine--tRNA ligase) (LEURS); Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.893
recQ
ATP-dependent DNA helicase RecQ.
  
 0.878
rpoA
RNA polymerase alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.733
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.
 
 0.676
recA
RecA protein (Recombinase A); 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.
  
 0.648
ligB
DNA ligase B; Catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. Belongs to the NAD-dependent DNA ligase family. LigB subfamily.
