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. (614 aa)    
Predicted Functional Partners:
rpoD-2
RNA polymerase sigma factor RpoD (Sigma-70); 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.
  
 0.968
dnaB-2
Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.
 
 0.955
dnaB
Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.
 
 0.953
rpoS
RNA polymerase, sigma S (sigma 38) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
 0.882
rpoD
RNA polymerase sigma-70 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
 0.864
engA
GTP-binding protein EngA; GTPase that plays an essential role in the late steps of ribosome biogenesis; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. EngA (Der) GTPase family.
   
  
 0.828
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.
 
  
 0.753
rph
Ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.
    
 
 0.729
rpoH
RNA polymerase, sigma 32 (sigma H) factor; Function of homologous gene experimentally demonstrated in an other organism; factor.
  
 0.675
trmD
tRNA (guanine-N(1)-)-methyltransferase; Specifically methylates guanosine-37 in various tRNAs. Belongs to the RNA methyltransferase TrmD family.
 
  
 0.642
