Summary

LightOnC.glu is a programmable light-responsive genetic circuit for Corynebacterium glutamicum that regulates gene expression in response to light signaling. It uses light-controlled RNA-binding proteins to build light-controlled transcription factors for dynamic transcriptional control.

Usefulness & Problems

Why this is useful

This tool provides optogenetic control of transcription in Corynebacterium glutamicum, enabling dynamic and programmable regulation without relying solely on conventional chemical induction. The reported platform also enabled engineered synthesis of chitin oligosaccharides and chondroitin sulphate oligosaccharides A in this host.

LightOnC.glu is a gene expression regulation system in Corynebacterium glutamicum that uses light-controlled RNA-binding proteins to construct light-controlled transcription factors.

Problem solved

It addresses the lack of a programmable light-responsive gene regulation platform in Corynebacterium glutamicum. The system supports dynamic control of engineered metabolic or regulatory networks based on light signaling.

Published Workflows

Objective: Develop dynamic light-controlled gene regulation tools in Corynebacterium glutamicum and apply them to rebalance metabolic flow for oligosaccharide production.

Why it works: The abstract frames the workflow around using light-responsive regulation to dynamically balance cell growth and product synthesis, then coupling that control to engineered synthesis pathways and a light-controlled bioreactor for production.

Stages

  1. 1.
    Establish light-controlled gene expression system(functional_characterization)

    This stage establishes the core optogenetic expression-control capability needed before applying dynamic regulation to metabolic pathways.

    Selection: Construction of light-controlled transcription factors using light-controlled RNA-binding proteins in C. glutamicum.

  2. 2.
    Develop light-controlled gene interference system(functional_characterization)

    This stage adds a second regulatory mode, gene interference, to expand dynamic control over metabolic flow.

    Selection: Development of a high-performance light-controlled gene interference system using CRISPR/Cpf1 tools.

  3. 3.
    Design synthesis network for target oligosaccharide production(library_design)

    This stage connects the optogenetic control systems to a production objective by engineering the synthesis network for desired oligosaccharides.

    Selection: Metabolic flow in the synthesis network was designed to enable CHOS and CSA production in C. glutamicum.

  4. 4.
    Bioreactor production validation(confirmatory_validation)

    This stage confirms that the light-responsive system functions under production conditions and yields high CHOS titer.

    Selection: Construction of a light-controlled bioreactor and measurement of CHOS production titer.

Objective: Develop dynamic, broadly applicable, minimally toxic light-responsive gene regulation in Corynebacterium glutamicum and use it to rebalance metabolic flow between growth and product synthesis.

Why it works: The workflow couples light-responsive control of gene expression and gene interference to dynamically redirect metabolic flow between growth and production states in C. glutamicum.
