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 [...] (736 aa)    
Predicted Functional Partners:
leuS
leucyl-tRNA synthetase (leuS); Similar to GB:L42023 SP:P43827 PID:1006043 PID:1221027 PID:1205168 percent identity: 45.93; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 
 0.977
ssb
Single-strand DNA-binding protein (ssb); 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.
  
 
 0.955
rpoA
DNA-directed RNA polymerase, alpha subunit (rpoA); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.944
recA
Recombinase (recA); 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.
  
 0.912
polA
DNA polymerase I (polA); In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
 
 0.903
dnaN
DNA polymerase III beta-subunit (dnaN); Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiat [...]

Conserved hypothetical protein; Similar to GB:L77117 SP:Q58708 PID:1591951 percent identity: 34.23; identified by sequence similarity; putative.
  
    0.841
HP_1022
Predicted coding region HP1022; Hypothetical protein; identified by GeneMark; putative.
  
 0.836
HP_0353
Flagellar export protein (fliH); Similar to PID:1146263 SP:P52611 GB:AE000783 percent identity: 28.49; identified by sequence similarity; putative.
   
 
 0.805
rnhA
Ribonuclease H (rnhA); Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.
