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

alkAProbable bifunctional transcriptional activator/DNA repair enzyme AlkA; Is involved in the adaptive response to alkylation damage in DNA caused by alkylating agents. Repairs the Sp diastereomer of DNA methylphosphotriester lesions by a direct and irreversible transfer of the methyl group to one of its own cysteine residues. Also catalyzes the 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 (By similarity); In the C-terminal sect [...] (496 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.

dinX
Probable DNA polymerase IV DinX (pol IV 1) (DNA nucleotidyltransferase (DNA-directed)); Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII (By similarity).

xthA
Probable exodeoxyribonuclease III protein XthA (exonuclease III) (EXO III) (AP endonuclease VI); Rv0427c, (MTCY22G10.24c), len: 291 aa. Probable xthA (alternate gene name: xth), exodeoxyribonuclease III protein (see citation below), similar to others e.g. EX3_ECOLI|P09030 exodeoxyribonuclease III from Escherichia Coli strain K12 (268 aa), FASTA scores: opt: 360, E(): 1.2e-17, (29.3% identity in 270 aa overlap); etc. Belongs to the AP/EXOA family of DNA repair enzymes.
  
 0.894
recA
RecA protein (recombinase A) [contains: endonuclease PI-MTUI (MTU RecA intein)]; Can catalyze 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. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.
  
 
 0.860
polA
Probable DNA polymerase I PolA; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
 
 0.836
dinP
DNA polymerase IV 2; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII (By similarity).

Rv1318c
Possible adenylate cyclase (ATP pyrophosphate-lyase) (adenylyl cyclase); Rv1318c, (MTCY130.03c), len: 541 aa. Possible adenylate cyclase. Some similarity at the c-terminus to CYAA_RHIME|P19485 adenylate cyclase from Rhizobium meliloti (193 aa), FASTA scores, opt: 270, E(): 2.5e-11, (28.8% identity in 184 aa overlap); similar to other mycbacterium tuberculosis putative adenylate cyclases e.g. Rv1319c|MTCY130.04c (535 aa), FASTA scores: opt: 2505, E(): 0, (71.0% identity in 534 aa overlap), also similar to Rv1320c|MTCY130.05c (567 aa), FASTA scores, opt: 2423, E(): 0, (68.7% identity in [...]

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.
  
  
 0.783
uvrA
Probable excinuclease ABC (subunit A-DNA-binding ATPase) UvrA; 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. Alone it slightly inhibits RecA-mediated DNA strand exchange, in concert with UvrD1 greatly inhibits RecA-mediated DNA strand exchange. Belongs to the ABC transporter superfamily. UvrA family.
