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. Has a preference for oxidized pyrimidines, such as thymine glycol (prefers 5S isomers) 5,6-dihydrouracil:G, 5-hydroxyuracil:G, 5- hydroxycytosine:G and urea [...] (245 aa)    
Predicted Functional Partners:
mutY
Probable adenine glycosylase MutY; Adenine glycosylase active on G:A and C:A mispairs, as well as processing 7,8-dihydro-8-oxoguanine:A (8-oxoG) mismatches. Minor activity against 8-oxoG:G and 8-oxo:T mismatches is also seen. Bind dsDNA oligonucleotides containing the above mismatches.

nei
Probable endonuclease VIII Nei; 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 AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-strand break at the site of the removed base with both 3'- and 5'-phosphates (By similarity). Complements an E.coli nei nth double mutant.

fpg
Probable formamidopyrimidine-DNA glycosylase Fpg (FAPY-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) when paired with C, G or T, as well as methyl-faPy (formanidopyrimidine residues) in poly(dG-dC) and spiroiminodihydantoin:C base pairs. Unlike its E.coli ortholog has no activity on 8-oxoG:A. Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves [...]

Rv3673c
Rv3673c, (MTV025.021c), len: 227 aa. Possible membrane protein, thioredoxin-like protein (thiol-disulfide interchange protein), equivalent to Q9CB93|ML2300 putative membrane protein from Mycobacterium leprae (215 aa), FASTA scores: opt: 978, E(): 2.5e-52, (71.15% identity in 215 aa overlap). Some similarity with thioredoxin-related proteins e.g. P35160|RESA_BACSU RESA protein from Bacillus subtilis (181 aa), FASTA scores: opt: 212, E(): 5.7e-06, (30.55% identity in 108 aa overlap); Q9RXW6|DR0189 thiol:disulfide interchange protein from Deinococcus radiodurans (185 aa) FASTA scores: opt [...]

nei1
Possible DNA glycosylase; Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. DNA glycosylase that recognizes and removes damaged pyrimidines. Excises Tg:A (thymine glycol, prefers 5R isomers), Tg:G, 5,6-dihydrouracil:G base pairs and urea:A, also excises oxidized purine derivatives guanidinohydantoin:C and spiroiminodihydantoin:C. Poorly cleaves dsDNA with uracil substitutions, thus also acting as a weak uracil-DNA glycosylase. Acts on DNA bubble and 3'-fork structures, suggesting a role in replication-associated DNA repair. Activity on 7,8-dihydro-8-o [...]
