STRINGSTRING
topA protein (Sinorhizobium fredii NGR234) - STRING interaction network
"topA" - DNA topoisomerase 1 in Sinorhizobium fredii NGR234
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:
some 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 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 1; 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 super [...] (890 aa)    
Predicted Functional Partners:
rnr
Ribonuclease R; 3’-5’ exoribonuclease that releases 5’-nucleoside monophosphates and is involved in maturation of structured RNAs (788 aa)
   
   
  0.899
NGR_c10870
annotation not available (386 aa)
     
  0.879
recA2
Protein 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 (361 aa)
 
 
  0.838
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (336 aa)
     
 
  0.827
recQ
annotation not available (651 aa)
   
 
  0.822
rpoC
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1401 aa)
     
 
  0.821
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5’-3’ exonuclease activity (1040 aa)
