+ | [https://www.uniprot.org/uniprot/APTX_SCHPO APTX_SCHPO] DNA-binding protein involved in single-strand DNA break repair, double-strand DNA break repair and base excision repair. Resolves abortive DNA ligation intermediates formed either at base excision sites, or when DNA ligases attempt to repair non-ligatable breaks induced by reactive oxygen species. Catalyzes the release of adenylate groups covalently linked to 5'-phosphate termini, resulting in the production of 5'-phosphate termini that can be efficiently rejoined (By similarity). | ||

+ | == Publication Abstract from PubMed == | ||
+ | Aprataxin is a DNA deadenylase that resolves DNA 5'-AMP termini and reverses abortive DNA ligation. The crystal structures of Schizosaccharomyces pombe aprataxin Hnt3 in its apo form and in complex to dsDNA and dsDNA-AMP reveal how Hnt3 recognizes and processes 5'-adenylated DNA in a structure-specific manner. The bound DNA adopts a 5'-flap conformation that facilitates 5'-AMP access to the active site, where AMP cleavage occurs by a canonical catalytic mechanism. | ||
