STRINGSTRING
topA protein (Synechocystis sp. PCC6803) - STRING interaction network
"topA" - DNA topoisomerase I in Synechocystis sp. PCC6803
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 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 super [...] (898 aa)    
Predicted Functional Partners:
recQ
ATP-dependent DNA helicase RecQ; DNA helicase (478 aa)
   
  0.960
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3’ to 5’ and 5’ to 3’ exonuclease activity (986 aa)
 
  0.925
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 (354 aa)
 
  0.912
SYNGTS_1915
DNA polymerase III subunit (319 aa)
   
  0.892
rpoC2
DNA-directed RNA polymerase subunit beta’; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1317 aa)
     
 
  0.881
rpoC1
RNA polymerase gamma-subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (626 aa)
     
 
  0.876
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 (314 aa)
     
 
  0.850
cphA
Cyanophycin synthetase; Catalyzes the ATP-dependent polymerization of arginine and aspartate to multi-L-arginyl-poly-L-aspartic acid (cyanophycin; a water-insoluble reserve polymer) (873 aa)
   
 
  0.804
slr2059
Ferredoxin (134 aa)
              0.796
sbcC
Hypothetical protein; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3’->5’ double strand exonuclease that can open hairpins. It also has a 5’ single-strand endonuclease activity (1006 aa)
