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.

dnaGDNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. (581 aa)    
Predicted Functional Partners:
dnaB
Putative replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity and contains distinct active sites for ATP binding, DNA binding, and interaction with DnaC protein, primase, and other prepriming proteins.
 0.998
rpoD
Sigma D factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
  
 0.990
engA
Putative GTP-binding protein; GTPase that plays an essential role in the late steps of ribosome biogenesis.
  
  
 0.959
dnaX
DNA polymerase III, tau and gamma subunits; 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 (By similarity). [Isoform gamma]: chain seems to interact with the delta subunit to transfer the beta subunit on the DNA; Belongs to the DnaX/STICHEL family.
  
  
 0.921
dnaC
Chromosome replication protein; Initiation and chain elongation; similar to E. coli chromosome replication; initiation and chain elongation (AAC77317.1); Blastp hit to AAC77317.1 (245 aa), 93% identity in aa 1 - 245.
  
 
 0.914
rpsU
30S ribosomal protein S21. (SW:RS21_ECOLI); Belongs to the bacterial ribosomal protein bS21 family.
  
  
 0.911
rpoB
RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
  
 0.903
rpoS
Sigma S (sigma 38) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response.
  
 0.883
rplS
50S ribosomal subunit protein L19; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
  
  
 0.871
polA
DNA polymerase I; 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.
 
  
 0.871
