Abstract (English)

Many hydrolases found in nature have Zn(II) ions at their active site. Artificial hydrolases as alternatives for non-enzymatic hydrolysis were prepared by attaching Zn(II) cyclen complexes with an alcohol pendant to a polymeric support. These modified polymers showed a 10E4 fold enhanced intrinsic reactivity for the hydrolysis of phosphodiesters over the non-catalysed reaction in ...

Translation of the abstract (German)

Viele natürliche Hydrolasen haben Zn(II) in ihrem aktiven Zentrum. Künstliche Hydrolasen, die als Alternativen für nicht-enzymatische Hydrolysen verwendet werden, bestehen oft aus festphasen-gebundenem Zn(II)-Cyclen. Studien mit diesem System zeigten eine 10E4-fache Beschleunigung der Hydrolyse-Geschwindigkeit von Phosphorsäurediestern im Vergleich zu nicht katalysierten Reaktionen in Lösung. ...
