Purpose of the Study:

To develop a high-throughput, fluorescence-based method for enzyme expression and screening.
To enable rapid, one-pot, microscale expression and screening of industrial enzymes.
To provide a protocol for integrating cell-free protein expression with enzyme activity screening.

Main Methods:

Developed a one-pot, microscale protocol for enzyme expression and screening.
Integrated cell-free protein expression with fluorescence-based activity assays.
Utilized both 96-well plate and microscale-array formats for screening.

Main Results:

Successfully established a high-throughput method for industrial enzyme screening.
The protocol allows for rapid, first-pass screening of enzyme libraries.
Enabled detailed mechanistic analysis, including kinetics and temperature optima.

Conclusions:

The developed method significantly addresses the bottleneck in enzyme engineering.
This approach facilitates accelerated discovery and optimization of industrial enzymes.
The protocol is versatile for both high-throughput screening and mechanistic studies.
