Researchers have developed a synthetic biology technique that transforms linear messenger RNA into circular RNA structures within microbial cells. This circular configuration protects the mRNA from degradation and results in up to six-fold increases in protein production compared to traditional linear mRNA. The technology involves engineering cells to circularize mRNA internally, enhancing the stability and longevity of the genetic material used for protein synthesis.


This advancement could significantly improve biomanufacturing processes by enabling microbial cell factories to produce therapeutic proteins, enzymes, and other valuable biological products more efficiently and cost-effectively. The technology has potential applications in pharmaceutical production, industrial biotechnology, and any field requiring high-yield protein expression systems.


A synthetic biology technology has been developed that converts easily degraded messenger RNA (mRNA) into a ring-shaped form inside microbial cells, increasing protein production.
