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

alkBDNA repair system specific for alkylated DNA; Dioxygenase that repairs alkylated DNA and RNA containing 3- methylcytosine or 1-methyladenine by oxidative demethylation. Has highest activity towards 3-methylcytosine. Has lower activity towards alkylated DNA containing ethenoadenine, and no detectable activity towards 1-methylguanine or 3-methylthymine. Accepts double-stranded and single-stranded substrates. Requires molecular oxygen, alpha- ketoglutarate and iron. Provides extensive resistance to alkylating agents such as MMS and DMS (SN2 agents), but not to MMNG and MNU (SN1 agents) (B [...] (216 aa)    
Predicted Functional Partners:
alkA
Inducible; similar to E. coli 3-methyl-adenine DNA glycosylase II, inducible (AAC75129.1); Blastp hit to AAC75129.1 (282 aa), 74% identity in aa 1 - 279.
     
 0.959
ada
O6-methylguanine-DNA 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; In the C-terminal section; belongs to the MGMT family.
 
  
 0.959
aidB
Putative acyl-CoA dehydrogenase; Adaptive response; transcription activated by Ada; similar to E. coli putative acyl coenzyme A dehydrogenase (AAC77144.1); Blastp hit to AAC77144.1 (546 aa), 85% identity in aa 8 - 544.
   
  
 0.901
yojI
ATPase component; similar to E. coli putative ATP-binding component of a transport system (AAC75271.1); Blastp hit to AAC75271.1 (547 aa), 90% identity in aa 1 - 547.
      0.851
ogt
O-6-alkylguanine-DNA; 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.
  
  
 0.767
lexA
SOS response regulator; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-3'. In the presence of single- stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
      
 0.720
apbE
Putative thiamine biosynthesis lipoprotein; Flavin transferase that catalyzes the transfer of the FMN moiety of FAD and its covalent binding to the hydroxyl group of a threonine residue in a target flavoprotein such as NqrB and NqrC, two subunits of the NQR complex; Belongs to the ApbE family.
       0.687
dinP
DNA polymerase IV; 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.
      
 0.574
apbA
Ketopantoate reductase; Catalyzes the NADPH-dependent reduction of ketopantoate into pantoic acid. Has a strong preference for NADPH over NADH as the electron acceptor. Pantoate, ketoisovalerate, oxaloacetate, pyruvate, 3-hydroxypyruvate, alpha-ketoglutarate, alpha-ketobutyrate, and acetaldehyde cannot serve as substrates for reduction.

STM2573
Putative ketopantoate reductase; Catalyzes the NADPH-dependent reduction of ketopantoate into pantoic acid.
