Crystal structure of aprataxin ortholog Hnt3 from Schizosaccharomyces pombe
Template:ABSTRACT PUBMED 21984208
Function
[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).
