How can AI-designed peptides address the issue of protein misfolding and aggregation in *E. coli*?

The Bottleneck in Biomanufacturing: Protein Expression

For decades, Escherichia coli (E. coli) has been the workhorse of biomanufacturing, utilized for the large-scale production of therapeutic proteins, industrial enzymes, and research reagents.However, achieving high-yield protein expression in E. coli remains a important challenge. Common issues include:

* protein misfolding and aggregation: Leading to inclusion body formation and reduced functional protein.

* Proteolytic degradation: Host cell proteases can degrade the target protein.

* Codon bias: Differences in codon usage between the host and the gene of interest can limit translation efficiency.

* Metabolic burden: High-level protein expression can strain cellular resources.

These limitations drive the need for innovative strategies to optimize E. coli protein production. Recent advancements in artificial intelligence (AI) and peptide design are offering groundbreaking solutions.
