Harnessing yeast organelles for metabolic engineering

Area of Science:

• Synthetic biology and metabolic engineering in yeast.
• Cellular compartmentalization and organelle engineering.

Background:

• Yeast metabolic engineering traditionally focuses on the cell cytosol.
• Subcellular compartments offer unique physiochemical environments and compositions.
• Growing interest in leveraging yeast's subcellular compartmentalization for enhanced metabolic functions.

Purpose of the Study:

• To review the current state of yeast subcellular engineering.
• To highlight the benefits of targeting biosynthetic pathways to specific organelles.
• To compare subcellularly engineered yeast strains with native producers and cytosolic engineered strains.

Main Methods:

• Review of existing literature on yeast subcellular engineering.
• Analysis of performance data from strains engineered for organelle-specific pathways.
• Comparative assessment of different subcellular compartments (mitochondria, peroxisomes, ER/Golgi, vacuoles, cell wall) in various yeast species.

Main Results:

• Subcellular engineering can eliminate metabolic crosstalk by physically separating pathways.
• Targeting pathways to organelles like mitochondria, peroxisomes, ER/Golgi, vacuoles, and the cell wall shows promise.
• Engineered strains demonstrate competitive or superior performance compared to native or cytosolic engineered counterparts.

Conclusions:

• Subcellular engineering in yeast presents significant advantages for metabolic pathway efficiency.
• Organelle targeting offers a powerful strategy to overcome limitations of cytosolic engineering.
• Further research is needed to make organelle engineering as mainstream as cytosolic engineering in academia and industry.
