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; 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 supe [...] (964 aa)    
Predicted Functional Partners:
uvrD
Putative DNA helicase II; Similar to Mycobacterium tuberculosis probable DNA helicase II homolog UvrD or Rv3198c or MT3291 or MTV014.42c SW:UVRD_MYCTU (O53344) (700 aa) fasta scores: E(): 2.7e-133, 58.92% id in 689 aa, and to Escherichia coli DNA helicase II UvrD or MutU or PdeB or Rad or RecL or B3813 SW:UVRD_ECOLI (P03018) (720 aa) fasta scores: E(): 7.8e-37, 32.16% id in 656 aa.
 
 0.993
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; Belongs to the RecA family.
   
 0.903
rpoC
DNA-directed RNA polymerase beta' chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.883
rpoB
DNA-directed RNA polymerase beta chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.862
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
 0.850
DIP1026
Similar to Mycobacterium leprae hypothetical protein ML1120 TR:Q9CC83 (EMBL:AL583920) (873 aa) fasta scores: E(): 1.9e-14, 28.49% id in 888 aa, and to Mycobacterium tuberculosis hypothetical 93.4 kDa protein Rv1278 or MT1315 or MTCY50.04c SW:YC78_MYCTU (Q11042) (875 aa) fasta scores: E(): 3.3e-13, 29% id in 893 aa. Contains coiled-coil domains, and thus some probably non-specific similarity to e.g. Drosophila melanogaster myosin heavy chain, non-muscle zip SW:MYSN_DROME (Q99323) (2017 aa) fasta scores: E(): 5.7e-07, 23.06% id in 568 aa.
  
 0.828
rpoA
DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.784
rpoZ
Putative DNA-directed RNA polymerase omega chain; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
 
 
 
 0.784
leuS
Similar to Escherichia coli leucyl-tRNA synthetase LeuS or B0642 SWALL:SYL_ECOLI (SWALL:P07813) (860 aa) fasta scores: E(): 1.9e-37, 37.53% id in 967 aa, and to Streptomyces coelicolor leucyl-tRNA synthetase LeuS SWALL:Q9RDL5 (EMBL:AL136518) (966 aa) fasta scores: E(): 1.6e-209, 59.93% id in 971 aa; Belongs to the class-I aminoacyl-tRNA synthetase family.

pheT
Similar to Mycobacterium tuberculosis phenylalanyl-tRNA synthetase beta chain PheT or Rv1650 or MT1688 or MTCY06H11.15 SWALL:SYFB_MYCTU (SWALL:P94985) (831 aa) fasta scores: E(): 4.2e-156, 49.64% id in 844 aa, and to Bacillus subtilis phenylalanyl-tRNA synthetase beta chain PheT SWALL:SYFB_BACSU (SWALL:P17922) (804 aa) fasta scores: E(): 1.8e-53, 30.69% id in 847 aa.
