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

NSP_20DNA 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 [...] (387 aa)    
Predicted Functional Partners:
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.
 
 0.999
dnaA
Chromosomal replication initiator protein DnaA; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids. Belongs to the DnaA family.
 
 0.998
NSP_18930
DNA polymerase III delta prime subunit; Nsp18930; ORF_ID:nsp18930.
 
 0.997
mutS
DNA mismatch repair protein MutS; This protein is involved in the repair of mismatches in DNA. It is possible that it carries out the mismatch recognition step. This protein has a weak ATPase activity.
  
 0.995
NSP_46920
DNA polymerase III delta subunit; Nsp46920; ORF_ID:nsp46920.
  
 
 0.992
dnaX
DNA polymerase III subunits gamma and tau; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity.
 
 
 0.985
NSP_19350
Amino-terminal intein-mediated trans-splice / DNA polymerase III alpha subunit; Nsp19350; ORF_ID:nsp19350.
  
 
 0.979
recA
RecA protein; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.
  
 0.979
NSP_8500
Exodeoxyribonuclease III; Nsp8500; ORF_ID:nsp8500.
   
 0.978
NSP_45290
DNA polymerase III alpha subunit / Carboxy-terminal intein-mediated trans-splice; Nsp45290; ORF_ID:nsp45290.
  
 
 0.976
