Project: Yeast Artifical Organell
+
<!----------------------
-
Synthetic biologists have been engineering genes and pathways in the cell to let it perform functions they desire. However, these man-made pathways incorporated in cytoplasm may suffer inferences from the original genes and pathways within the cell. Eukaryotic cells have organells that separate important pathways from that in the cytoplasm. Thus we want to make our own organells that perform the designed function. There has been some works on man-made organells, however this year the team of Shenzhen plan to create our man-made organell and apply it to organic synthesis by engineering yeast mitochondria, which we call Yeast Artificial Organell, and YAO for short.

<< Project Introduction

A short video introducing our project, Yeast Artificial Organelle #1.0.


Background

        This year, our team focuses on one of the major problems we faced in synthetic biology. When a synthetic pathway is introduced into the cell, it may somehow disturb the original system. On the other hand, the original system may prevent the synthetic pathway from working as expected. People are trying many different ways to solve this problem. One of them is to learn from eukaryotic organelles, using membrane structures to separate synthetic pathways to reduce interferences. However we think that a simple membrane is not enough for a cell factory.

Figure 1. Inferences between synthetic pathway and original systems.

        So our idea is to construct a real semiautonomous organelle from the natural one, yeast mitochondrion, we call it Yeast Artificial Organelle, and YAO for short.

Project: YAO

        When YAO works as an organelle factory, it inherits some key features from mitochondrion, as membrane structure and semi-self-replication. Its genome and transport systems have to be engineered into artificial ones to meet our needs, as called YAO.Genome and YAO.Channel.

Figure 2. YAO.Genome and YAO.Channel.

        Proteins needed in YAO are produced by YAO.Genome, or by nucleus and transported into YAO via YAO.Channel.

Figure 3. Proteins with signal peptide transported into YAO via YAO.Channel.

        As Moreover, we also want our YAO to have new properties. we hope it can sense its status, send signals out and also respond to signals sent into it so it can be regulated. We call it YAO.Sensor.

Project stories p4.jpg

Figure 4. Production accumulates and YAO.Sensor works.

        As production accumulates to max, YAO.Sensor can tell the situation to nucleus, and initial a suicide for bio-safety purpose. This is the second new property, YAO.Suicider.

Project stories p5.jpg

Figure 5. YAO.Sensor works and initials cell death.

        And finally we want to combine all these components, YAO.Genome, YAO.Channel, YAO.Sensor and YAO.Suicider into a YAO.Factory to prove that YAO is more safe , stable and effective in biosynthesis.
