AlkB homolog 3-mediated tRNA demethylation promotes protein synthesis in cancer cells [PDF]
The mammalian AlkB homolog (ALKBH) family of proteins possess a 2-oxoglutarate- and Fe(II)-dependent oxygenase domain. A similar domain in the Escherichia coli AlkB protein catalyzes the oxidative demethylation of 1-methyladenine (1-meA) and 3 ...

Repair of Methylation Damage in DNA and RNA by Mammalian AlkB Homologues [PDF]
Human and Escherichia coli derivatives of AlkB enzymes remove methyl groups from 1-methyladenine and 3-methylcytosine in nucleic acids via an oxidative mechanism that releases the methyl group as formaldehyde. In this report, we demonstrate that the mouse homologues of the alpha-ketoglutarate Fe(II) oxygen-dependent enzymes mAbh2 and Abh3 have ...

DNA repair by bacterial AlkB proteins
The Escherichia coli AlkB protein is an iron- and 2-oxoglutarate-dependent oxygenase, repairing 1-methyladenine and 3-methylcytosine lesions in DNA. AlkB homologues are present in a number of bacterial species, and some bacteria have two different AlkB proteins.

Differential repair of etheno-DNA adducts by bacterial and human AlkB proteins [PDF]
AlkB proteins are evolutionary conserved Fe(II)/2-oxoglutarate-dependent dioxygenases, which remove alkyl and highly promutagenic etheno(ɛ)-DNA adducts, but their substrate specificity has not been fully determined. We developed a novel assay for the repair of ɛ-adducts by AlkB enzymes using oligodeoxynucleotides with a single lesion and specific DNA ...

Structural and mutational analysis of Escherichia coli AlkB provides insight into substrate specificity and DNA damage searching. [PDF]
BACKGROUND: In Escherichia coli, cytotoxic DNA methyl lesions on the N1 position of purines and N3 position of pyrimidines are primarily repaired by the 2-oxoglutarate (2-OG) iron(II) dependent dioxygenase, AlkB.

Structure and function prediction of human homologue hABH5 of _E. coli_ ALKB5 using in silico approach [PDF]
Newly discovered human homologues of ALKB protein have shown the activity of DNA damaging drugs, used for cancer therapy. Little is known about the structure and function of hABH5, one of the members of this superfamily.

The AlkB Homolog SlALKBH10B Negatively Affects Drought and Salt Tolerance in Solanum lycopersicum
ALKBH proteins, the homologs of Escherichia coli AlkB dioxygenase, constitute a single-protein repair system that safeguards cellular DNA and RNA against the harmful effects of alkylating agents.

Non-homologous functions of the AlkB homologs [PDF]
The DNA repair enzyme AlkB was identified in E. coli more than three decades ago. Since then, nine mammalian homologs, all members of the superfamily of alpha-ketoglutarate and Fe(II)-dependent dioxygenases, have been identified (designated ALKBH1-8 and FTO). While E.
