Coordinating precursor supply for pharmaceutical polyketide production in Streptomyces

Area of Science:

• Microbiology
• Biotechnology
• Synthetic Biology

Background:

• Polyketide pharmaceuticals, vital in medicine and agriculture, are primarily produced by Streptomyces species.
• These compounds are secondary metabolites with low yields, often limited by precursor availability.
• Precursor pathways are critical targets for improving polyketide production.

Purpose of the Study:

• To review recent advances in engineering precursor pathways for enhanced polyketide production.
• To discuss strategies for optimizing precursor supply in Streptomyces and other bacteria.
• To highlight the integration of precursor enhancement with other factors for efficient biosynthesis.

Main Methods:

• Review of native and heterologous precursor pathways in Streptomyces.
• Analysis of synthetic biology approaches for precursor engineering.
• Discussion of tools and strategies for precursor-supply enhancement.

Main Results:

• Identification of diverse precursor pathways amenable to engineering.
• Demonstration of precursor pathway rewiring for increased polyketide titers.
• Highlighting the importance of coordinating precursor supply with biosynthesis.

Conclusions:

• Engineering precursor pathways is crucial for boosting polyketide production in Streptomyces.
• Synthetic biology offers powerful tools for designing 'cell-factories' for efficient pharmaceutical manufacturing.
• Optimized precursor supply is essential for the industrial viability of polyketide drugs.
