STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.

topADNA topoisomerase I (topA) {Bacillus subtilis; 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 stra [...] (761 aa)    
Predicted Functional Partners:
MJ_1554
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 42.23; identified by sequence similarity; putative.
    
 0.927
rpa
Replication factor A related protein; Probably plays an essential for replication of the chromosome, DNA recombination and repair (By similarity). Binds approximately 20 nucleotides.
 
 
 0.905
rad50
Purine NTPase; Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Rad50 controls the balance between DNA end bridging and DNA resection via ATP-dependent structural rearrangements of the Rad50/Mre11 complex; Belongs to the SMC family. RAD50 subfamily.
 
 0.894
MJ_0585
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0585.
  
 0.881
radB
DNA repair protein REC; Involved in DNA repair and in homologous recombination. May regulate the cleavage reactions of the branch-structured DNA. Has a very weak ATPase activity that is not stimulated by DNA. Binds DNA but does not promote DNA strands exchange (By similarity).
  
 0.880
radA
DNA repair protein RAD51 (radA); Involved in DNA repair and in homologous recombination. Binds and assemble on single-stranded DNA to form a nucleoprotein filament. Hydrolyzes ATP in a ssDNA-dependent manner and promotes DNA strand exchange between homologous DNA molecules.
  
 0.880
smc
Chromosome segretation protein (smc1); Required for chromosome condensation and partitioning. Belongs to the SMC family.
 
 
 0.845
rpoK
DNA-directed RNA polymerase, subunit K (rpoK); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Belongs to the archaeal RpoK/eukaryotic RPB6 RNA polymerase subunit family.
   
 
 0.831
rpoA2
DNA-directed RNA polymerase, subunit A'' (rpoA2); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.831
leuS
leucyl-tRNA synthetase (leuS); Similar to SP:P26637 PID:1370340 PID:1403549 PID:3508 percent identity: 35.17; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
