STRINGSTRING
topA protein (Desulfovibrio vulgaris Hildenborough) - STRING interaction network
"topA" - DNA topoisomerase 1 in Desulfovibrio vulgaris Hildenborough
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 [...] (760 aa)    
Predicted Functional Partners:
recD2
ATP-dependent RecD-like DNA helicase; DNA-dependent ATPase and ATP-dependent 5’-3’ DNA helicase. Has no activity on blunt DNA or DNA with 3’-overhangs, requires at least 10 bases of 5’-ssDNA for helicase activity (742 aa)
 
 
  0.903
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 (347 aa)
     
 
  0.887
polA
DNA polymerase I; Identified by similarity to SP-P00582; match to protein family HMM PF00476; match to protein family HMM PF01367; match to protein family HMM PF02739; match to protein family HMM TIGR00593 (1015 aa)
 
 
  0.884
gyrB
DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner (798 aa)
   
 
  0.880
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 (357 aa)
 
 
  0.878
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP (238 aa)
   
   
  0.875
rpsE
30S ribosomal protein S5; With S4 and S12 plays an important role in translational accuracy; Belongs to the universal ribosomal protein uS5 family (163 aa)
   
 
  0.832
lepA
Elongation factor 4; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back- translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner (601 aa)
   
   
  0.817
rpsK
30S ribosomal protein S11; Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine-Dalgarno cleft in the 70S ribosome (129 aa)
   
   
  0.813
DVU_0453
DNA helicase; Identified by match to protein family HMM PF00580 (1070 aa)
   
 
  0.808
