STRINGSTRING
xthA protein (Escherichia coli K12 MG1655) - STRING interaction network
"xthA" - Exodeoxyribonuclease III in Escherichia coli K12 MG1655
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

xthAExodeoxyribonuclease III; Major apurinic-apyrimidinic endonuclease of E.coli. It removes the damaged DNA at cytosines and guanines by cleaving on the 3’-side of the AP site by a beta-elimination reaction. It exhibits 3’-5’-exonuclease, 3’-phosphomonoesterase, 3’-repair diesterase and ribonuclease H activities (268 aa)    
Predicted Functional Partners:
nth
Endonuclease 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 (211 aa)
 
 
 
  0.968
nfo
Endonuclease 4; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic sites (AP sites) to produce new 5’-ends that are base-free deoxyribose 5-phosphate residues. It preferentially attacks modified AP sites created by bleomycin and neocarzinostatin (285 aa)
     
 
  0.954
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3’-5’ and 5’-3’ exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template (928 aa)
   
 
  0.937
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 (229 aa)
     
 
  0.914
recA
Protein RecA; Required for homologous recombination and the bypass of mutagenic DNA lesions by the SOS response. Catalyzes ATP-driven homologous pairing and strand exchange of DNA molecules necessary for DNA recombinational repair. Catalyzes 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. The SOS response controls an apoptotic-like death (ALD) induced (in the absence of the mazE-mazF toxin-antitoxin module) in response to DNA damaging agen [...] (353 aa)
   
 
  0.864
ygdG
Flap endonuclease Xni; Has flap endonuclease activity, but does not seem to have exonuclease activity. During DNA replication, flap endonucleases cleave the 5’-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5’-end of a downstream Okazaki fragment (251 aa)
     
 
  0.822
uvrA
UvrABC system protein A; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by UvrB, the UvrA molecules dissociate (940 aa)
   
   
  0.816
mutM
Formamidopyrimidine-DNA glycosylase; 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 7,8-dihydro-8-oxoguanine (8-oxoG) and its derivatives such as guanidinohydantoin-C and spiroiminodihydantoin-C, however it also acts on thymine glycol-G, 5,6-dihydrouracil-G and 5-hydroxyuracil-G. Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-s [...] (269 aa)
   
   
  0.812
mutY
Adenine DNA glycosylase; Adenine glycosylase active on G-A mispairs. MutY also corrects error-prone DNA synthesis past GO lesions which are due to the oxidatively damaged form of guanine- 7,8-dihydro-8- oxoguanine (8-oxo-dGTP) (350 aa)
     
 
  0.809
alkA
DNA-3-methyladenine glycosylase 2; Hydrolysis of the deoxyribose N-glycosidic bond to excise 3-methyladenine, 3-methylguanine, 7-methylguanine, O2- methylthymine, and O2-methylcytosine from the damaged DNA polymer formed by alkylation lesions (282 aa)
