Adenosine Glycosidase, Polynucleotide

N-Glycosidases that remove adenines from Ribosomal RNA, depurinating the conserved alpha-sarcin loop of 28S Ribosomal RNA. They often consist of a toxic A subunit and a binding lectin B subunit. They may be considered as Protein Synthesis Inhibitors. They are found in many Plants and have cytotoxic and antiviral activity.
