GEDpm-cg

GEDpm-cg designs in-silico genomic single-nucleotide point mutations in Corynebacterium glutamicum to support precise genome editing workflows using suicide plasmid-mediated counter-selection and overlap-based DNA assembly for vector construction and experimental verification.

Key Features:

• Comprehensive design capability: Generates precise designs for single-nucleotide edits at any locus on the C. glutamicum chromosome using a suicide plasmid-mediated counter-selection strategy combined with overlap-based DNA assembly.
• High-throughput in-silico processing: Performs computational design tasks for over 10,000 single point mutations in approximately five minutes.
• Primer and verification design: Produces primer sequences for overlap-based vector DNA assembly and for sequencing verification of edits.
• Experimental validation: In-silico designs were validated by successful construction of three independent point mutations in C. glutamicum.

Scientific Applications:

• Microbial cell factory development: Enables targeted genomic modifications in C. glutamicum for strain engineering.
• Metabolic engineering: Supports precise single-nucleotide changes to optimize metabolic pathways.
• Synthetic biology: Facilitates design and verification of genetic variants and engineered constructs.
• Industrial strain optimization: Supports large-scale mutation analysis for industrial applications using C. glutamicum.

Methodology:

Uses computer-aided design tools to generate in-silico designs for suicide plasmid-mediated counter-selection, overlap-based DNA assembly for vector construction, and primer sequences for assembly and sequencing verification.
