title: Selective hydrolysis of tRNA by ethylenediamine bound to a DNA oligomer.
abstract: A sequence-selective artificial ribonuclease was prepared by attaching ethylenediamine to the 5'-end of a DNA oligomer as the sequence-recognizing moiety. The hybrid, incorporating a 19-mer DNA which is complementary with the A44-A62 sequence of tRNA(Phe), hydrolyzed the tRNA selectively at the 3'-side of C63.
