WAS BEDEUTET RIBOZYME AUF ENGLISCH
Ribozym
Ein Ribozym ist ein RNA-Molekül, das in der Lage ist, spezifische biochemische Reaktionen zu katalysieren, ähnlich der Wirkung von Proteinenzymen. Die 1982 entdeckte Ribozyme zeigten, dass RNA sowohl genetisches Material als auch ein biologischer Katalysator sein kann und zur RNA-Welthypothese beigetragen hat, was darauf hindeutet, dass RNA in der Evolution von präbiotischen Selbstreplikationssystemen wichtig gewesen sein könnte. Als katalytische RNA bezeichnet man auch Ribozyme im Ribosom, um Aminosäuren während der Proteinsynthese zu verknüpfen und in einer Vielzahl von RNA-Reaktionen, einschließlich RNA-Spleißung, viraler Replikation und Transfer-RNA-Biosynthese. Beispiele für Ribozyme sind das Hammerhead-Ribozym, das VS-Ribozym und das Haarnadel-Ribozym. Forscher, die den Ursprung des Lebens studieren, haben im Laboratorium Ribozyme produziert, die in der Lage sind, ihre eigene Synthese unter sehr spezifischen Bedingungen, wie einem RNA-Polymerase-Ribozym, zu katalysieren. Mutagenese und Selektion wurde durchgeführt, was zu einer Isolierung von verbesserten Varianten des "Round-18" -Polymerase-Ribozyms aus 2001 führte. "B6.

promoters selected for regulation of ribozyme expression can often be assessed
empirically, at least in part, by transient transfection studies in cell culture. A
common approach is to examine the levels of ribozyme expression obtained by ...

Thomas' Hematopoietic Cell Transplantation
Two ribozymes, the hammerhead ribozyme and the hairpin ribozyme, have been
extensively studied due to their small size and rapid kinetics. Their application
has been recently reviewed in several publications (reviewed in [107-110]).
