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.

topADNA topoisomerase I; 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 [...] (905 aa)    
Predicted Functional Partners:
recQ
ATP-dependent DNA helicase RecQ; Identified by similarity to SP:P15043; match to protein family HMM PF00270; match to protein family HMM PF00271; match to protein family HMM TIGR00614; match to protein family HMM TIGR01389.
  
 0.951
recA
recA protein; 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.
  
 0.885
pcrA
ATP-dependent DNA helicase PcrA; Identified by match to protein family HMM PF00580; match to protein family HMM TIGR01073.
 
 
 0.867
sync_1174
RecF/RecN/SMC N terminal domain protein.
  
 0.848
rpoA
DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.820
smc
Chromosome segregation protein SMC; Required for chromosome condensation and partitioning. Belongs to the SMC family.
  
 
 0.804
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.
 
 0.802
rpoB
DNA-directed RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.791
leuS
leucyl-tRNA synthetase; Identified by match to protein family HMM PF00133; match to protein family HMM TIGR00396; Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.783
sync_2115
Hypothetical protein; Identified by Glimmer2; putative.
       0.773
