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

dnaIPrimosomal protein DnaI; Identified by match to protein family HMM PF07319. (299 aa)    
Predicted Functional Partners:
dnaC
Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.
  
 
 0.987
SGO_0509
Replication initiation and membrane attachment protein (DnaB) superfamily; Identified by match to protein family HMM PF07261.
 
  
 0.885
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 of [...]
 
  
 0.873
nrdR
Transcriptional regulator, NrdR family; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family.
       0.800
SGO_0511
NADPH-flavin oxidoreductase -like protein; Identified by match to protein family HMM PF00881; Belongs to the flavin oxidoreductase frp family.
       0.800
SGO_1003
DNA replication protein DnaD; Identified by match to protein family HMM PF04271; match to protein family HMM TIGR01446.
 
  
 0.745
polI
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.
     
 0.692
dnaK
DnaK chaperone protein; Acts as a chaperone; Belongs to the heat shock protein 70 family.
   
  
 0.691
der
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.
       0.677
