Microbial skeletal editing: hints for arene reconstruction from actinobacteria

Area of Science:

• Organic Synthesis
• Biochemistry
• Drug Discovery

Background:

• Organic synthesis is advancing skeletal editing for rapid drug discovery.
• Microorganisms have long used structure modification to modulate bioactivity.

Purpose of the Study:

• To demonstrate that actinobacteria's biosynthetic machinery performs skeletal editing.
• To analyze and categorize natural skeletal editing pathways.
• To compare natural and synthetic skeletal editing methods.

Main Methods:

• Analysis of biosynthetic pathways in actinobacteria.
• Categorization of skeletal editing transformations (e.g., atom swaps, deletions, reorganizations).
• Focus on monooxygenase enzymes and angucycline polyketide modification.

Main Results:

• Actinobacteria utilize skeletal editing logic (atom swap/addition/deletion) via natural pathways.
• Four distinct groups of transformations were identified.
• The AlpJ enzyme family exemplifies diversity-oriented skeletal editing in angucycline polyketides.

Conclusions:

• Natural skeletal editing by microbes offers a blueprint for synthetic chemistry.
• Understanding enzymatic logic can inspire new late-stage modification methods.
• This bridges natural and synthetic repertoires for complex molecule synthesis.
