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; 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 [...] (866 aa)    
Predicted Functional Partners:
recQ
Similar to Escherichia coli ATP-dependent DNA helicase RecQ or b3822 SWALL:RECQ_ECOLI (SWALL:P15043) (607 aa) fasta scores: E(): 1.4e-198, 80.66% id in 605 aa.
  
 0.981
ECA0824
Similar to Rhodospirillum rubrum pyruvate-flavodoxin oxidoreductase NifJ SWALL:NIFJ_RHORU (SWALL:Q53046) (1191 aa) fasta scores: E(): 0, 54.73% id in 1182 aa, and to Escherichia coli probable pyruvate-flavodoxin oxidoreductase ydbk or b1378 SWALL:NIFJ_ECOLI (SWALL:P52647) (1174 aa) fasta scores: E(): 0, 78.79% id in 1174 aa. Also similar to ECA2957 (47.377% id. in 1182 aa overlap).
  
   0.951
ssb
Single-strand binding 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.
  
 
 0.951
leuS
Similar to Escherichia coli leucyl-tRNA synthetase LeuS or b0642 SWALL:SYL_ECOLI (SWALL:P07813) (860 aa) fasta scores: E(): 0, 84.3% id in 860 aa; Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.921
gltB
Similar to Escherichia coli glutamate synthase [NADPH] large chain precursor GltB or AspB SWALL:GLTB_ECOLI (SWALL:P09831) (1517 aa) fasta scores: E(): 0, 86.75% id in 1495 aa, and to Yersinia pestis glutamate synthase, large subunit GltB SWALL:AAM83722 (EMBL:AE013613) (1535 aa) fasta scores: E(): 0, 90.25% id in 1498 aa.
  
  
 0.890
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.
 
 0.785
polA
Putative DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
 0.765
recG
Putative ATP-dependent DNA helicase; Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3'- to 5'- polarity. Unwinds branched duplex DNA (Y- DNA); Belongs to the helicase family. RecG subfamily.
 
  
 0.754
rplI
50S ribosomal protein L9; Binds to the 23S rRNA.
 
   
 0.752
rpoA
DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
