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

mutTPutative NTP pyrophosphohydrolase; 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). Functions, in conjunction with ytkD, to protect vegetatively growing cells from DNA-damaging agents such as H(2)O(2) or t-BHP (t-butylhydroperoxide). The 2 proteins do not [...] (149 aa)    
Predicted Functional Partners:
mutY
A/G-specific adenine glycosylase or DNA-(apurinic or apyrimidinic site) lyase; Base excision repair (BER) glycosylase that initiates repair of A:oxoG to C:G by removing the inappropriately paired adenine base from the DNA backbone, generating an abasic site product. 8-oxoguanine (oxoG) is a genotoxic DNA lesion resulting from oxidation of guanine; this residue is misread by replicative DNA polymerases, that insert adenine instead of cytosine opposite the oxidized damaged base. Shows a powerful dicrimination of A versus C, since it does not cleave cytosine in oxoG:C pairs. May also be a [...]

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 [...]

mutL
DNA mismatch repair factor; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of a final effector complex (By similarity). Overexpression of mutSL partially suppresses the high spontaneous mutation frequency of a ytkD/mutM/mutY triple disruption which lacks the system required to prevent damage by oxidized guanine (8-oxo [...]

ogt
O6-alkylguanine DNA alkyltransferase; 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.
     
 0.771
recJ
Putative single-strand DNA-specific exonuclease; Putative single-stranded-DNA-specific exonuclease (By similarity). RecA thread formation during DNA double-strand break repair requires RecJ or AadAB; Belongs to the RecJ family.
  
  
 0.630
ydaO
Putative metabolite transporter; High-affinity potassium transporter.
  
    0.607
ydaP
Putative enzyme with pyruvate as substrate; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
    0.591
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
  
  
 0.573
recA
Multifunctional SOS repair factor; Multifunctional protein involved in homologous recombination, DNA repair and competence. Can catalyze the hydrolysis of (d)ATP in the presence of single-stranded DNA; prefers dATP at least in vitro, catalyzes the dATP-dependent uptake of single- stranded DNA by duplex DNA, and the dATP-dependent hybridization of homologous single-stranded DNAs (strand exchange). RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP. It interacts with LexA causing its activation and leading to its autocatalytic clea [...]

yvcI
Putative triphosphate pyrophosphate hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the Nudix hydrolase family.
