Twister P1 ribozyme, from 10.1080/15476286.2022.2123640
Introduction
The twister ribozyme is an RNA molecule that is capable of self-cleavage at specific sites.The RNA exhibits nucleolytic ribozyme activity both in vitro and in vivo, with cleavage rates comparable to those of other nucleolytic ribozymes[1]. This grants it the ability to regulate polycistronic co-expression system[2]
Usage and Biology
The Twister ribozyme is a crucial component of ribozyme-assisted polycistronic co-expression system.
We incorporate the twister ribozyme between the coding CDSs in a polycistron. This ribozyme cleaves the polycistronic mRNA transcript, converting them into individual mono-cistrons. This process eliminates interactions between the cistrons, ensuring each mono-cistron has a comparable translation initiation rate. Subsequently, in conjunction with the RBS designed by the software RAP, we can modulate the translation initiation rate of individual mono-cistrons, enabling precise adjustment of the pRAP co-expression system.
