Recent studies have shown that RNA hydrolysis is remarkably promoted by metal ions and suitably designed metal complexes. We have found that autocleavage of dipeptides X-Ser and a tripeptide Gly-Ser-Ala is catalyzed by Zn(II) at 70 degrees C and pH 7.0. A mechanistic analogy between metal ion-catalyzed hydrolysis of peptides and RNA is suggested.
