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-dependent; 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. (659 aa)    
Predicted Functional Partners:
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 [...]

dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
     
 0.852
dnaX
DNA polymerase III, subunit gamma and tau; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity; Belongs to the DnaX/STICHEL family.
     
 0.842
leuS
leucyl-tRNA synthetase; Identified by similarity to SP:P36430; match to protein family HMM PF00133; match to protein family HMM TIGR00396; Belongs to the class-I aminoacyl-tRNA synthetase family.
   
 
 0.826
cysS
cysteinyl-tRNA synthetase; Identified by similarity to SP:Q06752; match to protein family HMM PF01406; match to protein family HMM TIGR00435; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.825
MG_252
RNA methyltransferase, TrmH family, group 3; Identified by similarity to EGAD:57207; match to protein family HMM PF00588; match to protein family HMM PF08032; match to protein family HMM TIGR00186; Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family.

dnaN
DNA polymerase III, beta subunit; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of [...]
      
 0.778
gyrA
DNA gyrase, A subunit; 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.
  
  
 0.743
uvrD
UvrD/REP helicase; Has both ATPase and helicase activities. Unwinds DNA duplexes with 3' to 5' polarity with respect to the bound strand and initiates unwinding most effectively when a single-stranded region is present. Involved in the post-incision events of nucleotide excision repair and methyl-directed mismatch repair (By similarity); Belongs to the helicase family. UvrD subfamily.
  
  
 0.728
glyS
glycyl-tRNA synthetase; Catalyzes the attachment of glycine to tRNA(Gly). Belongs to the class-II aminoacyl-tRNA synthetase family.
