Title:
BACTERIAL CONTINUOUS EVOLUTION SYSTEM, ORTHOGONAL ERROR-PRONE DNA POLYMERASE, AND CONTINUOUS EVOLUTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/041031
Kind Code:
A1
Abstract:
The present invention relates to a bacterial continuous evolution system, an orthogonal error-prone DNA polymerase, and a continuous evolution method. According to the present invention, after an orthogonal DNA replication system is combined with an orthogonal error-prone DNA polymerase, what is obtained is a continuous evolution method that is capable of comprising all mutation types and realizing long DNA fragment mutation and features high continuity and simple and convenient operation. By means of inducing opening and closing of DNA polymerase expression, switching between a linear plasmid error-prone mutation process and a high-fidelity replication process is achieved, thereby achieving the efficient continuous evaluation of a target DNA sequence.
