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 ...

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

DNA Repair, 2012 2-Oxoglutarate (2OG) and iron (Fe(II)) dependent dioxygenases catalyze a wide range of biological oxidations, including hydroxylation and demethylation of proteins and nucleic acids. AlkB from Escherichia coli directly reverses certain methyl lesions in DNA, and defines a subfamily of 2OG/Fe(II) dioxygenases that has so far been shown to be involved in

The N6-Methyladenosine RNA Demethylase AlkB Homolog 5 (ALKBH5) in Metabolic Diseases: Molecular Mechanisms and Pharmacological Implications-A Review. [PDF]
BiomoleculesMetabolic diseases, including type 2 diabetes mellitus (T2DM) and metabolic dysfunction-associated fatty liver disease (MAFLD), are chronic disorders characterized by dysregulated glucose and lipid homeostasis and represent major contributors to insulin resistance, cardiovascular complications, and liver injury.

International Journal of Molecular SciencesN6-methyladenosine (m6A) is an abundant and pervasive post-transcriptional modification in eukaryotic mRNAs. AlkB homolog (ALKBH) proteins play crucial roles in RNA metabolism and translation, participating in m6A methylation modification to regulate plant development.

Frontiers in Cell and Developmental Biology, 2021 The AlkB family consists of Fe(II)- and α-ketoglutarate-dependent dioxygenases that can catalyze demethylation on a variety of substrates, such as RNA and DNA, subsequently affecting tumor progression and prognosis.

Role of the Demethylase AlkB Homolog H5 in the Promotion of Dentinogenesis
Frontiers in Physiology, 2022 Dentinogenesis is a key process in tooth formation and is regulated by a series of pre- and post-transcriptional regulations. N6-methyl-adenosine (m6A), which is the most prevalent internal chemical modification that can be removed by the RNA demethylase AlkB homolog H5 (ALKBH5), has recently been reported to be involved in several biological processes.

Human ALKBH4 interacts with proteins associated with transcription. [PDF]
PLoS ONE, 2012 The Fe(II)- and 2-oxoglutarate (2OG)-dependent dioxygenase AlkB from E. coli is a demethylase which repairs alkyl lesions in DNA, as well as RNA, through a direct reversal mechanism. Humans possess nine AlkB homologs (ALKBH1-8 and FTO). ALKBH2 and ALKBH3

Bioinformatic mapping of AlkB homology domains in viruses [PDF]
BMC Genomics, 2005 Abstract Background AlkB-like proteins are members of the 2-oxoglutarate- and Fe(II)-dependent oxygenase superfamily. In Escherichia coli the protein protects RNA and DNA against damage from methylating agents.
