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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ligADNA ligase (NAD(+)); DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA. (675 aa)    
Predicted Functional Partners:
rsmB
Ribosomal RNA small subunit methyltransferase B; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
  
 0.947
leuS
Leucyl-tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 
 0.882
NIDE1291
ATP-dependent DNA helicase; Function of strongly homologous gene; enzyme.
  
  
 0.800
NIDE2038
Conserved protein of unknown function, putative AAA-5 ATPase; Homologs of previously reported genes of unknown function; 9927482.
  
    0.787
NIDE2037
Homologs of previously reported genes of unknown function.
       0.773
topA
DNA 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 [...]

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.
 
   
 0.724
ruvB
Holliday junction ATP-dependent DNA helicase RuvB; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing.
  
   
 0.637
gatA
Glutamyl-tRNA(Gln) amidotransferase, subunit A; Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu- tRNA(Gln).
  
    0.579
murC
UDP-N-acetylmuramate-L-alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
  
 
 0.533
