Outline What is synthetic biology? Biological Clocks The “Repressilator” Signal transduction The “Diverter”

What is synthetic biology?  The design and construction of new biological parts, devices, and systems  The “Repressilator”  The re-design of existing, natural biological systems for useful purposes.  The “Diverter”

Outline What is synthetic biology? Biological Clocks The “Repressilator” Signal transduction The “Diverter”

Biological - Clocks  Three questions 1. How does it work 2. How does it synchronize 3. How does it translate to activity

Biological - Clocks

Outline What is synthetic biology? Biological Clocks The “Repressilator” Signal transduction The “Diverter”

The “Repressilator”

Repressilator  oscillations are favored by Strong promoters Efficient ribosome-binding sites Tight transcriptional repression Comparable protein and mRNA decay rates

Repressilator

Outline What is synthetic biology? Biological Clocks The “Repressilator” Signal transduction The “Diverter”

Signal Transduction

The Yeast system  Scaffold proteins  Mediating recruitment  Improve efficiency of signal transfer.  Facilitate interactions among different signal pathways  Control localization of signal proteins within a cell.
