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

RP720DNA LIGASE (lig); 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. (689 aa)    
Predicted Functional Partners:
RP776
DNA POLYMERASE I (polA); In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.
 
   
 0.882
RP421
LEUCYL-TRNA SYNTHETASE (leuS); Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 
 0.868
RP447
DNA HELICASE II (uvrD); 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.
  
  
 0.844
RP326
DNA TOPOISOMERASE I (topA); 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 D [...]

RP247
UDP-N-ACETYLMURAMATE--ALANINE LIGASE (murC); Cell wall formation; Belongs to the MurCDEF family.
  
 
 0.689
RP152
GLUTAMYL-tRNA AMIDOTRANSFERASE SUBUNIT A (gatA); 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) (By similarity).
  
    0.688
RP734
ATP-DEPENDENT NUCLEASE SUBUNIT A (addA).
  
 
 0.662
RP835
EXCINUCLEASE ABC SUBUNIT A (uvrA); The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by UvrB, the UvrA molecules dissociate.
  
 
 0.657
RP298
DNA MISMATCH REPAIR PROTEIN MUTS (mutS); This protein is involved in the repair of mismatches in DNA. It is possible that it carries out the mismatch recognition step. This protein has a weak ATPase activity (By similarity).
  
  
 0.620
RP598
TRANSCRIPTION-REPAIR COUPLING FACTOR (mfd); Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site; In the N-terminal section; belongs to the UvrB family.
