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

dnaQThe epsilon subunit of DNA polymerase III is responsible of the proofreading 3'-5' exonuclease activity; The DNA polymerase III or replicase is responsible for most of the replicative synthesis in bacteria. It exhibits a DNA polymerase activity (alpha chain) and a 3' to 5' exonuclease proofreading activity; Localized in the cytoplasm; High confidence in function and specificity. (218 aa)    
Predicted Functional Partners:
dnaN
DNA polymerase III, beta chain; 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 r [...]

CAZ97974.1
Conserved protein containing a N-terminal cyclic nucleotide-binding domain, a central CBS domain and a C-terminal DUF294 family domain. The cyclic nucleotide-binding domains are composed of three alpha-helices and a distinctive eight-stranded, antiparallel beta-barrel structure. CBS (cystathionine-beta-synthase) domains are small intracellular modules that pair together to form a stable globular domain. They bind ligands with an adenosyl group such as AMP, ATP and S-AdoMet and may play a regulatory role making proteins sensitive to adenosyl carrying ligands. DUF294 family proteins are [...]

dnaE1
The alpha subunit of DNA polymerase III is responsible of the polymerase activity; Contains a N-terminal exonuclease domain, a PHP domain (phosphoesterase) and a C-terminal OB module (oligonucleotide /oligosaccharide-binding fold) involved in the DNA binding; The DNA polymerase III or replicase is responsible for most of the replicative synthesis in bacteria. It also exhibits a 3' to 5' exonuclease proofreading activity; Localized in the cytoplasm; High confidence in function and specificity.

holB
The delta prime subunit of DNA polymerase III is part of the 'clamp' loading complex that assembles the beta processivity factor onto the primer template and plays a central role in the organization and communication at the replication fork; The DNA polymerase III or replicase is responsible for most of the replicative synthesis in bacteria. It also exhibits a 3' to 5' exonuclease proofreading activity; Localized in the cytoplasm; High confidence in function and specificity.
