alkB protein (Escherichia coli K12 MG1655) - STRING interaction network
"alkB" - Alpha-ketoglutarate-dependent dioxygenase AlkB in Escherichia coli K12 MG1655
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

Gene Fusion
alkBAlpha-ketoglutarate-dependent dioxygenase AlkB; 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) (216 aa)    
Predicted Functional Partners:
Bifunctional transcriptional activator/DNA repair enzyme Ada; Involved in the adaptive response to alkylation damage in DNA caused by alkylating agents. Repairs 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 (Cys-321). Also specifically repairs the Sp diastereomer of DNA methylphosphotriester lesions by the same mechanism, although the methyl transfer occurs onto a different cysteine residue (Cys-38). Cannot demethylate the other diastereome [...] (354 aa)
DNA-3-methyladenine glycosylase 2; 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 (282 aa)
ABC transporter ATP-binding/permease protein YojI; Mediates resistance to the antibacterial peptide microcin J25, when expressed from a multicopy vector. Functions as an efflux pump for microcin J25, with the help of the outer membrane channel TolC (547 aa)
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 (171 aa)
Putative acyl-CoA dehydrogenase AidB; Part of the adaptive DNA-repair response to alkylating agents. Could prevent alkylation damage by protecting DNA and destroying alkylating agents that have yet to reach their DNA target. Binds to double-stranded DNA with a preference for a DNA region that includes its own promoter. Shows weak isovaleryl-CoA dehydrogenase activity in vitro (541 aa)
FAD-protein FMN transferase; 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 (351 aa)
Endonuclease 4; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic sites (AP sites) to produce new 5’-ends that are base-free deoxyribose 5-phosphate residues. It preferentially attacks modified AP sites created by bleomycin and neocarzinostatin (285 aa)
Protein RecA; Required for homologous recombination and the bypass of mutagenic DNA lesions by the SOS response. Catalyzes ATP-driven homologous pairing and strand exchange of DNA molecules necessary for DNA recombinational repair. Catalyzes 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. The SOS response controls an apoptotic-like death (ALD) induced (in the absence of the mazE-mazF toxin-antitoxin module) in response to DNA damaging agen [...] (353 aa)
DNA recombination protein RmuC; Involved in DNA recombination (475 aa)
Uncharacterized protein YagL; DNA-binding protein (232 aa)
