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

rapARNA polymerase remodeling/recycling factor ATPase; Transcription regulator that activates transcription by stimulating RNA polymerase (RNAP) recycling in case of stress conditions such as supercoiled DNA or high salt concentrations. Probably acts by releasing the RNAP, when it is trapped or immobilized on tightly supercoiled DNA. Does not activate transcription on linear DNA. Probably not involved in DNA repair (By similarity); Belongs to the SNF2/RAD54 helicase family. RapA subfamily. (968 aa)    
Predicted Functional Partners:
rpoB
RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 0.995
rpoZ
RNA polymerase, omega subunit; 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.
   
 0.994
rpoA
RNA polymerase, alpha subunit; DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme.
   
 0.992
rpoC
RNA polymerase, beta prime subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
  0.954
rluA
Dual-specificity RNA pseudouridine synthase RluA; Dual specificity enzyme that catalyzes the synthesis of pseudouridine from uracil-746 in 23S ribosomal RNA and from uracil-32 in the anticodon stem and loop of transfer RNAs.
 
 
 0.946
yejH
Putative ATP-dependent DNA or RNA helicase; RadD contains helicase motifs, suggesting it may be a helicase, although that activity has not been observed (Probable). In combination with RadA is important in repair of double-strand DNA breaks (DSB). Has DNA-independent ATPase activity that is stimulated by single-stranded DNA-binding protein SSB. ATPase is stimulated by a peptide with the last 10 residues of SSB, but not when the peptide's last Phe residue is missing. Binds ssDNA; binding is slightly better in the presence of nucleotides. May be involved in resolution of branched DNA int [...]

polA
5' to 3' DNA polymerase and 3' to 5'/5' to 3' exonuclease; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template.
  
 0.892
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. DNA bound in the ring is bent 22 degrees, in solution primed DNA is bound more tightly than dsDNA, suggesting the clamp binds both ss- and dsDNA. In a complex of DNA with this protein, alpha, epsilon and tau subunits however the DNA is only slightly bent. Coordinates protein traffic at the replicati [...]
  
 0.820
polB
DNA polymerase II; Thought to be involved in DNA repair and/or mutagenesis. Its processivity is enhanced by the beta sliding clamp (dnaN) and clamp loader.
 
 0.818
udk
Uridine/cytidine kinase; Protein involved in nucleobase, nucleoside and nucleotide interconversion; Belongs to the uridine kinase family.
