The goal of the input team is to improve the binding and switching activity of the BlaCaM protein with respect to a previously non-functional analyte. A successful evolution would demonstrate the ability of the BlaCaM switch to sense different molecules, highlighting its potential as a biosensor component. BlaCaM is a fusion of two proteins, a calmodulin center with two halves of β-lactamase attached to the N- and C-termini. Calmodulin displays large conformational changes when it binds to both calcium and varying peptides. These conformational changes adjust the position of the two β-lactamase halves relative to each other, greatly affecting the activity of the enzyme. The ability to turn on or off the activity of the attached enzyme depending on the presence of an analyte gives the BlaCaM protein the ability to act as a sensor. By evolving BlaCaM to bind to different peptides or small molecules, the protein can be made into a sensor for a wide array of compounds.  Adapting the BlaCaM switch is performed via directed evolution, where random mutations of the switch are screened and selected for increased effectiveness, and this process is iterated until a satisfactory new switch has been created.

Introduction

Input

The goal of the input team is to improve the binding and switching activity of the BlaCaM protein with respect to a previously non-functional analyte. A successful evolution would demonstrate the ability of the BlaCaM switch to sense different molecules, highlighting its potential as a biosensor component. BlaCaM is a fusion of two proteins, a calmodulin center with two halves of β-lactamase attached to the N- and C-termini. Calmodulin displays large conformational changes when it binds to both calcium and varying peptides. These conformational changes adjust the position of the two β-lactamase halves relative to each other, greatly affecting the activity of the enzyme. The ability to turn on or off the activity of the attached enzyme depending on the presence of an analyte gives the BlaCaM protein the ability to act as a sensor. By evolving BlaCaM to bind to different peptides or small molecules, the protein can be made into a sensor for a wide array of compounds. Adapting the BlaCaM switch is performed via directed evolution, where random mutations of the switch are screened and selected for increased effectiveness, and this process is iterated until a satisfactory new switch has been created.
