Characterization of a Trypanosoma brucei Alkb homolog capable of repairing alkylated DNA [PDF]
Experimental Parasitology, 2012 Trypanosoma brucei encodes a protein (denoted TbABH) that is homologous to AlkB of Escherichia coli and AlkB homolog (ABH) proteins in other organisms, raising the possibility that trypanosomes catalyze oxidative repair of alkylation-damaged DNA. TbABH was cloned and expressed in E.

AlkB homolog 3-mediated tRNA demethylation promotes protein synthesis in cancer cells [PDF]
Scientific Reports, 2017 AbstractThe 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-methylcytosine (3-meC) in both DNA and RNA.

An alkB gene homolog is differentially transcribed during the Caulobacter crescentus cell cycle [PDF]
Journal of Bacteriology, 1997 A Caulobacter crescentus alkB gene homolog was identified in a clone previously shown to contain the heat shock genes dnaK and dnaJ; the homolog is located upstream of dnaK and is transcribed in the opposite orientation. An analysis of the alkB gene has shown that the deduced amino acid sequence is that of a 21-kDa protein, which is 42% identical and ...

Novel AlkB dioxygenases--alternative models for in silico and in vivo studies.
PLoS ONE, 2012 BackgroundALKBH proteins, the homologs of Escherichia coli AlkB dioxygenase, constitute a direct, single-protein repair system, protecting cellular DNA and RNA against the cytotoxic and mutagenic activity of alkylating agents, chemicals significantly ...

Functional diversity of 2-oxoglutarate/Fe(II)-dependent dioxygenases in plant metabolism [PDF]
, 2014 Oxidative enzymes catalyze many different reactions in plant metabolism. Among this suite of enzymes are the 2-oxoglutarate/Fe(II)-dependent dioxygenases (2-ODDs). Cytochromes P450 (CYPs) as often considered the most versatile oxidative enzymes in nature,

Adaptive Response Enzyme AlkB Preferentially Repairs 1-Methylguanine and 3-Methylthymine Adducts in Double-Stranded DNA [PDF]
, 2018 The AlkB protein is a repair enzyme that uses an α-ketoglutarate/Fe(II)-dependent mechanism to repair alkyl DNA adducts. AlkB has been reported to repair highly susceptible substrates, such as 1-methyladenine and 3-methylcytosine, more efficiently in ss ...

Role of the viral AlkB homologs in RNA repair [PDF]
, 2014 AlkB proteins that repair DNA via reversing methylation damage are conserved in a broad range of prokaryotes and eukaryotes including plants. Surprisingly, AlkB-domains were discovered in the genomes of numerous plant positive-strand RNA viruses, majority of which belong to the family Flexiviridae. The major goal of this research was to reveal the AlkB

Human AlkB Homolog 1 Is a Mitochondrial Protein That Demethylates 3-Methylcytosine in DNA and RNA [PDF]
Journal of Biological Chemistry, 2008 The Escherichia coli AlkB protein and human homologs hABH2 and hABH3 are 2-oxoglutarate (2OG)/Fe(II)-dependent DNA/RNA demethylases that repair 1-methyladenine and 3-methylcytosine residues. Surprisingly, hABH1, which displays the strongest homology to AlkB, failed to show repair activity in two independent studies.
