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 I (topA); 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 D [...] (663 aa)    
Predicted Functional Partners:
AF_0780
Predicted coding region AF_0780; Hypothetical protein; identified by GeneMark; putative.
 
 0.937
rad50
Purine NTPase, putative; Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Rad50 controls the balance between DNA end bridging and DNA resection via ATP-dependent structural rearrangements of the Rad50/Mre11 complex; Belongs to the SMC family. RAD50 subfamily.
  
 0.922
AF_0382
Conserved hypothetical protein; Similar to GB:L77117 PID:1500014 percent identity: 26.69; identified by sequence similarity; putative.
  
 0.898
radB
DNA repair protein REC; Involved in DNA repair and in homologous recombination. May regulate the cleavage reactions of the branch-structured DNA. Has a very weak ATPase activity that is not stimulated by DNA. Binds DNA but does not promote DNA strands exchange (By similarity).
 
 0.891
AF_0817
Conserved hypothetical protein; Similar to GB:L77117 PID:1500447 percent identity: 42.53; identified by sequence similarity; putative.
    
 0.880
AF_2418
DNA repair protein, putative; Similar to GB:U64315 SP:Q92889 PID:1524411 PID:1905924 percent identity: 28.86; identified by sequence similarity; putative.
    
 0.880
radA
DNA repair protein RAD51 (radA); Involved in DNA repair and in homologous recombination. Binds and assemble on single-stranded DNA to form a nucleoprotein filament. Hydrolyzes ATP in a ssDNA-dependent manner and promotes DNA strand exchange between homologous DNA molecules (By similarity).
  
 0.868
leuS
leucyl-tRNA synthetase (leuS); Similar to GB:L77117 SP:Q58050 PID:1591345 percent identity: 49.68; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.867
mre11
DNA repair protein RAD32 (rad32); Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Mre11 binds to DSB ends and has both double-stranded 3'-5' exonuclease activity and single-stranded endonuclease activity. Belongs to the MRE11/RAD32 family.
  
 0.843
smc
Chromosome segregation protein (smc1); Required for chromosome condensation and partitioning. Belongs to the SMC family.
