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

nthEndonuclease III; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate; Belongs to the Nth/MutY family. (219 aa)    
Predicted Functional Partners:
exoA
Apurinic/apyrimidinic endonuclease; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
 
 0.993
nfo
Type IV apurinic/apyrimidinic endonuclease; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate.
  
 
 0.975
mutM
formamidopyrimidine-DNA glycosidase; Involved in the GO system responsible for removing an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine, 8-oxo- dGTP) from DNA and the nucleotide pool. 8-oxo-dGTP is inserted opposite dA and dC residues of template DNA with almost equal efficiency thus leading to A.T to G.C transversions (By similarity). Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. Acts as DNA glycosylase that recognizes and removes damaged bases. Has a preference for oxidized purines, such as 8-oxo-dGTP. Has AP (apurinic/apyrimidi [...]

dnaD
DNA-remodelling primosomal protein; Probable component of primosome involved in the initiation of DNA replication.
  
  
 0.967
ypoC
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.858
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
 
 
 0.839
yonN
Putative HU-related DNA-binding protein; Histone-like DNA-binding protein which is capable of wrapping DNA to stabilize it, and thus to prevent its denaturation under extreme environmental conditions; Belongs to the bacterial histone-like protein family.
     
 0.731
polX
DNA polymerase/3'-5' exonuclease X; Strictly DNA-template-directed DNA polymerase, preferentially acting on DNA structures containing gaps from one to a few nucleotides and bearing a phosphate group at the 5' end of the downstream DNA. The fact that PolX is able to conduct filling of a single-nucleotide gap, allowing further sealing of the resulting nick by a DNA ligase, points to a putative role in base excision repair (BER) during the B.subtilis life cycle. Moreover, also possesses a 3'-5' exonuclease activity able to edit unpaired 3'-termini in a gapped DNA substrate and likely invo [...]
  
  
 0.704
ung
uracil-DNA glycosylase; Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine; Belongs to the uracil-DNA glycosylase (UDG) superfamily. UNG family.
  
 
 0.667
asnS
asparaginyl-tRNA synthetase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
