		+	== Publication Abstract from PubMed ==
		+	Eukaryotic type II topoisomerases (Top2alpha and Top2beta) are homodimeric enzymes; essential for altering DNA topology by the formation of normally transient double-strand DNA cleavage. Anticancer drugs (etoposide, doxorubicin, and mitoxantrone), but also Top2 oxidation and DNA helical alterations cause potentially irreversible Top2-DNA cleavage complexes (Top2cc), leading to Top2-linked DNA breaks. Top2cc are the therapeutic mechanism for killing cancer cells. Yet, Top2cc can also generate recombination, translocations and apoptosis in normal cells. The Top2 protein-DNA covalent complexes are excised (in part) by tyrosyl-DNA-phosphodiesterase 2 (TDP2/TTRAP/EAP2/VPg unlinkase). In this study, we show that irreversible Top2cc induced in suicidal substrates are not processed by TDP2 unless they first undergo proteolytic processing or denaturation. We also demonstrate that TDP2 is most efficient when the DNA attached to the tyrosyl is in a single-stranded configuration, and that TDP2 can efficiently remove a tyrosine linked to a single misincorporated ribonucleotide or to polyribonucleotides, which expands the TDP2 catalytic profile with RNA substrates. The 1.6 Angstrom resolution crystal structure of TDP2 bound to a substrate bearing a 5'-ribonucleotide defines a mechanism through which RNA can be accommodated in the TDP2 active site, albeit in a strained conformation.
