Area of Science:

• Biochemistry
• Molecular Biology
• Structural Biology

Background:

• Structural Genomics initiatives spurred parallelized laboratory techniques, enhancing single protein expression.
• Escherichia coli (E. coli) has re-emerged as a primary host for heterologous protein expression due to these advancements.
• Co-expression technologies for complex protein reconstitution in E. coli have been developed alongside single expression improvements.

Purpose of the Study:

• To provide a comprehensive overview of complex protein reconstitution and characterization using co-expression in E. coli.
• To highlight the need for automated, combinatorial experiments in co-expression technology assessments.
• To address the challenges in small-scale biophysical characterization for early-stage sample discrimination.

Main Methods:

• Adapting high-throughput approaches from single expression to co-expression technologies.
• Implementing combinatorial experiments with automated protocols.
• Utilizing small-scale biophysical characterization methods for early assessment.

Main Results:

• Co-expression technologies in E. coli benefit from high-throughput approaches.
• Automated protocols are essential for combinatorial experiments in co-expression.
• Early biophysical characterization enables cost-effective and time-saving sample discrimination.

Conclusions:
