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

Score
dnaGDNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. (617 aa)    
Predicted Functional Partners:
Athe_2432
PFAM: DnaB domain protein helicase domain protein; SMART: AAA ATPase; KEGG: ckl:CKL_3295 DNA helicase.
 0.959
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.
 
  
 0.950
Athe_0882
Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.
 0.944
Athe_0711
KEGG: csc:Csac_0881 deoxyguanosinetriphosphate triphosphohydrolase-like protein; TIGRFAM: deoxyguanosinetriphosphate triphosphohydrolase; PFAM: metal-dependent phosphohydrolase HD sub domain; SMART: metal-dependent phosphohydrolase HD region; Belongs to the dGTPase family. Type 2 subfamily.
     
 0.864
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.
    
 
 0.823
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
  
 0.805
Athe_0746
KEGG: tpd:Teth39_0089 hypothetical protein.
  
 
 0.804
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
  
 0.751
Athe_2423
TIGRFAM: RNA polymerase sigma factor, sigma-70 family; PFAM: Sigma-70 region 4 type 2; sigma-70 region 2 domain protein; KEGG: gur:Gura_2617 RpoD family RNA polymerase sigma factor.
 
  
 0.744
Athe_0473
TIGRFAM: small GTP-binding protein; PFAM: GTP-binding protein HSR1-related; Miro domain protein; KEGG: csc:Csac_1123 small GTP-binding protein.
   
  
 0.734
