Repurposing peroxisomes for microbial synthesis for biomolecules.

Microbial synthesis represents an alternative approach for the sustainable production of chemicals, fuels, and medicines. However, construction of biosynthetic pathways always suffers from side reactions, toxicity of intermediates, or low efficiency of substrate channeling. Subcellular compartmentalization may contribute to a more efficient production of target products by reducing side reactions and toxic effects within a compact insular space. The peroxisome, a type of organelle that is involved in catabolism of fatty acids and reactive oxygen species, has attracted a great deal of attention in the construction of eukaryotic cell factories with little impact on essential cellular function. In this chapter, we will systematically review recent advances in peroxisomal compartmentalization for microbial production of valuable biomolecules. Additionally, detailed experimental designs and protocols are also described. We hope a comprehensive understanding of peroxisomes will promote their application in metabolic engineering and synthetic biology.
