Novel RNA catalysts for the Michael reaction

Abstract: The ribozyme described here is the first example of a catalytic RNA with Michael-adduct forming activity which represents a key mechanistic step in metabolic pathways and other biochemical reactions. Therefore, previously unforeseen RNA-evolution pathways can be considered, for example the formation of dTMP from dUMP. The substrate specificity of this ribozyme may also render it useful in organic syntheses.

“…Selection amplification, or SELEX (Ellington and Szostak 1990;Robertson and Joyce 1990;Tuerk and Gold 1990;Ellington et al 2000), has revealed many novel reactions-carbon-carbon bond formation (Tarasow 1997;Sengle et al 2001), amide bond synthesis (Lohse and Szostak 1996;Wiegand et al 1997;Zhang and Cech 1997), acetyl-CoA synthesis (Jadhav and Yarus 2002), anhydride activation of carbonyl groups (Kumar and Yarus 2001), and aminoacyl-RNA synthesis both in cis (Illangasekare et al 1995;Yarus 1999a, 1999b) and in trans (Lee et al 2000). This list could easily be lengthened.…”

“…[6] Die Substrate der meisten natürlich hervorgegangenen Ribozyme sind ihrerseits ebenfalls RNAStränge. Im Unterschied dazu zeigen die künstlich entwickelten DNA-und RNAzyme die Fähigkeit, eine Vielzahl von Reaktionsarten [76] (wie Diels-Alder-Reaktionen, [77] Aldolreaktionen, [78] Michael-Additionen, [79] die Bildung von Nglycosidischen Bindungen [80] und Acetylierungen [81] ) zu katalysieren. Viele RNA-und DNAzyme ahmen auch die katalytische Funktion von echten Enzymen nach, darunter die der Cholesterol-Esterase, [82] der N-Glycosylase, [83] des sog.…”
