Human AlkB homologue 5 (ALKBH5) is RNA N6-methyladenine demethylase and not known to be involved in DNA repair.
WebThe interaction between AlkB and RecA was validated by yeast two-hybrid assay; size-exclusion chromatography and standard pull down experiment and was shown to be direct and mediated by the N-terminal domain of RecA. RecA binding results AlkB–RecA heterodimer formation and RecA–AlkB repairs alkylated DNA with higher efficiency than … WebNov 1, 2008 · Yang et al. [Nature 452 (2008) 961-966] have now solved the crystal structure of AlkB and human AlkB homolog 2 (hABH2) in complex with DNA using an ingenious crosslinking strategy to stabilize the DNA-protein complex. AlkB proteins have similar catalytic domains, but different DNA recognition motifs.
AlkB (Alkylation B) is a protein found in E. coli, induced during an adaptive response and involved in the direct reversal of alkylation damage. AlkB specifically removes alkylation damage to single stranded (SS) DNA caused by SN2 type of chemical agents. It efficiently removes methyl groups from 1-methyl adenines, 3-methyl cytosines in SS DNA. AlkB is an alpha-ketoglutarate-dependent hydroxylase, a superfamily non-haem iron-containing proteins. It oxidatively demethylates the D… WebMay 25, 2024 · Alkbh1 encodes a demethylase for N(6)-methyladenine.
