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. (603 aa)    
Predicted Functional Partners:
dnaC
Replicative DNA helicase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the helicase family. DnaB subfamily.
 0.997
sigA
RNA polymerase major sigma-43 factor (sigma-A); 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; Belongs to the sigma-70 factor family. RpoD/SigA subfamily.
  
 0.992
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. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation o [...]
 
   
 0.955
dnaI
Helicase loader; Probably involved in DNA replication.
  
 
 0.933
dnaB
Helicase loading protein; Probable component of primosome involved in the initiation of DNA replication. It is essential for both replication initiation and membrane attachment of the origin region of the chromosome and plasmid pUB110.
     
 0.930
dnaX
DNA polymerase III (gamma and tau subunits); DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria.
  
  
 0.882
polC
DNA polymerase III (alpha subunit); Required for replicative DNA synthesis. This DNA polymerase also exhibits 3' to 5' exonuclease activity; Belongs to the DNA polymerase type-C family. PolC subfamily.
     
 0.879
ssbA
Single-strand DNA-binding protein; Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism. Has a 20-fold higher affinity for ssDNA than SsbB; SsbA and DprA activate the homologuos DNA strand exchange function of RecA-ATP.
 
 
 
 0.876
yqxD
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 9387153; Belongs to the UPF0178 family.
  
  
 0.860
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
 
  
 0.838
