Towards T7 RNA polymerase (T7RNAP)-based expression system in yeast: challenges and opportunities

Area of Science:

• Synthetic biology
• Molecular biology
• Biotechnology

Background:

• Biological engineering and synthetic biology advance gene regulation and expression for cellular functions.
• Yeast is a model for eukaryotic protein expression, while bacteriophage T7RNAP is preferred for prokaryotic systems.
• Integrating T7RNAP into yeast could improve eukaryotic gene regulation understanding and expression efficiency.

Purpose of the Study:

• To review historical attempts at creating a T7RNAP-based yeast expression system.
• To overview recent advances in eukaryotic transcription and translation relevant to this goal.
• To highlight the potential of a successful T7RNAP yeast system for synthetic biology and biorefining.

Main Methods:

• Literature review of past research on T7RNAP in yeast.
• Analysis of current knowledge in eukaryotic transcription and translation.
• Identification of key challenges and potential solutions for system integration.

Main Results:

• Previous attempts to establish a T7RNAP-based yeast expression system have been unsuccessful.
• Advances in understanding eukaryotic gene regulation offer new possibilities.
• The review consolidates existing knowledge and identifies future research directions.

Conclusions:

• A functional T7RNAP expression system in yeast remains a significant challenge.
• Leveraging recent discoveries in eukaryotic molecular biology is crucial for success.
• This system would greatly enhance yeast's utility as a cell factory in synthetic biology and sustainable industries.
