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

mutT2Probable mutator protein MutT2 (7,8-dihydro-8-oxoguanine-triphosphatase) (8-oxo-dGTPase); May be 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. MutT specifically degrades 8-oxo- dGTP to the monophosphate (By similarity). In vitro has 8-oxo-dGTPase activity. (141 aa)    
Predicted Functional Partners:
ogt
Methylated-DNA--protein-cysteine methyltransferase; Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated.

mutT4
Possible mutator protein MutT4; May be 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 (By similarity). In vitro has dATPase rather than 8-oxo-dGTPase activity.

Rv1159A
Rv1159A, len: 94 aa. Unknown protein.

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 [...]

recD
RecBCD enzyme subunit RecD; A helicase/nuclease that prepares dsDNA breaks (DSB) for recombinational DNA repair. Binds to DSBs and unwinds DNA via a highly rapid and processive ATP-dependent bidirectional helicase activity. Unwinds dsDNA until it encounters a Chi (crossover hotspot instigator) sequence from the 3' direction. Cuts ssDNA a few nucleotides 3' to the Chi site. The properties and activities of the enzyme are changed at Chi. The Chi-altered holoenzyme produces a long 3'-ssDNA overhang and facilitates RecA-binding to the ssDNA for homologous DNA recombination and repair. Holo [...]

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.

narG
Respiratory nitrate reductase (alpha chain) NarG; The alpha chain is the actual site of nitrate reduction (Probable). Supports anaerobic growth of E.coli on glycerol in an E.coli mutant lacking endogenous nitrate reductase.
  
  
 0.469
recG
Probable ATP-dependent DNA helicase RecG; Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3'- to 5'- polarity. Unwinds branched duplex DNA (Y- DNA) (By similarity); Belongs to the helicase family. RecG subfamily.

tagA
Rv1210, (MTCI364.22), len: 204 aa. Probable tagA,DNA-3-methyladenine glycosidase I (see citation below),similar to several e.g. 3MG1_ECOLI|P05100 DNA-3-methyladenine glycosidase I from Escherichia coli (187 aa), FASTA scores: opt: 530, E(): 1.3e-27, (44.2% identity in 190 aa overlap); similar to Q49957 Mycobacterium leprae cosmid B1756 (192 aa), FASTA scores: opt: 1042, E(): 0, (80.2% identity in 192 aa overlap).

ligC
DNA ligase C; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase family.
