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

dnaGDNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. (613 aa)    
Predicted Functional Partners:
Psta_2666
Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.
 0.976
sigA
RNA polymerase, sigma 70 subunit, RpoD subfamily; 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.
  
 0.933
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.
    
 
 0.874
Psta_2413
RNA polymerase, sigma 70 subunit, RpoD subfamily; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
 0.813
der
Small GTP-binding protein; 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.
   
  
 0.779
sigA-2
RNA polymerase, sigma 70 subunit, RpoD subfamily; 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.
  
 0.777
Psta_2155
RNA polymerase, sigma 70 subunit, RpoD subfamily; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
 0.775
trmD
tRNA (guanine-N1)-methyltransferase; Specifically methylates guanosine-37 in various tRNAs. Belongs to the RNA methyltransferase TrmD family.
 
  
 0.752
Psta_2693
Hypothetical protein.
       0.727
Psta_2313
KEGG: gur:Gura_2507 DNA polymerase III, alpha subunit; TIGRFAM: DNA polymerase III, alpha subunit; PFAM: DNA polymerase III alpha subunit; PHP domain protein; nucleic acid binding OB-fold tRNA/helicase-type; SMART: phosphoesterase PHP domain protein.
