Implication

Demonstrates enhanced indigo yields in engineered Escherichia coli by optimizing transporter gene expression, suggesting a sustainable production approach.

Key Points

To optimize indigo biosynthesis in an engineered Escherichia coli strain by enhancing transporter gene expression.
Engineered Escherichia coli strain E216 with styAB genes and mdh gene on plasmid.
Overexpression of mtr and acrA genes to improve indigo yields.
CRISPR-Cas9 knockout of mtr and acrA to assess their effects on production.
Proteomic analysis comparing conditions with and without tryptophan supplementation.
Overexpression of mtr and acrA genes significantly increased indigo production.
Knocking out mtr and acrA genes reduced indigo yields, while complementation restored production.
Tryptophan supplementation led to upregulation of key proteins and enriched metabolic pathways.
