STRINGSTRING
topA protein (Idiomarina loihiensis) - STRING interaction network
"topA" - Topoisomerase IA in Idiomarina loihiensis
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

topATopoisomerase IA; 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 supercoi [...] (872 aa)    
Predicted Functional Partners:
rpoC
DNA-directed RNA polymerase beta’ subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1411 aa)
     
 
  0.961
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 (329 aa)
     
 
  0.959
recQ
Superfamily II DNA helicase (614 aa)
   
  0.954
polA
DNA polymerase I (921 aa)
   
  0.949
recA
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 (372 aa)
   
  0.929
IL0021
CDGSH-type zinc finger protein (170 aa)
 
 
  0.912
ftsY
Signal recognition particle GTPase; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). Interaction with SRP-RNC leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual components (449 aa)
 
   
  0.884
tig
Trigger factor; Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase (433 aa)
 
 
  0.869
pheT
Phenylalanyl-tRNA synthetase beta subunit (795 aa)
   
 
  0.868
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP (525 aa)
   
   
  0.865
