Imino proton NMR analysis of HDV ribozymes: nested double pseudoknot structure and Mg2+ ion-binding site close to the catalytic core in solution.

abstract：:Impaired DNA damage repair, especially deficient transcription-coupled nucleotide excision repair, leads to segmental progeroid syndromes in human patients as well as in rodent models. Furthermore, DNA double-strand break signalling has been pinpointed as a key inducer of cellular senescence. Several recent findings s...
