STRINGSTRING
topA protein (Dermacoccus nishinomiyaensis) - STRING interaction network
"topA" - DNA topoisomerase 1 in Dermacoccus nishinomiyaensis
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 [...] (940 aa)    
Predicted Functional Partners:
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5’-3’ exonuclease activity (889 aa)
 
 
  0.881
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 (339 aa)
   
 
  0.868
sbcD
Nuclease SbcCD subunit D; 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 (397 aa)
   
 
  0.848
HX89_06140
Endonuclease; Derived by automated computational analysis using gene prediction method- Protein Homology (608 aa)
   
 
  0.845
recA
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 (364 aa)
   
 
  0.843
HX89_07550
DEAD/DEAH box helicase; Derived by automated computational analysis using gene prediction method- Protein Homology (703 aa)
 
 
  0.832
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis (266 aa)
         
  0.820
pyrB
Aspartate carbamoyltransferase; Derived by automated computational analysis using gene prediction method- Protein Homology; Belongs to the ATCase/OTCase family (313 aa)
         
  0.813
HX89_13065
Uncharacterized protein; Derived by automated computational analysis using gene prediction method- Protein Homology (1151 aa)
 
   
  0.810
ffh
Signal recognition particle protein; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY; Belongs to the GTP-binding SRP family. SRP54 subfamily (538 aa)
