title: Development of 2'-o-methyloligoribonucleotide and peptide nucleic acid based artificial ribonucleases.
abstract: We have developed 2'-O-methyloligoribonucleotide and peptide nucleic acid (PNA) based artificial ribonucleases (OBAN's), which in presence of zinc or copper ions cleave a potential therapy target in leukemia, an M-BCR/ABL mRNA model. The OBAN's give turnover of substrate and are thus real enzymes. A copper ion based system even gives single site cleavage in the RNA-substrate.
