pan-Draft

pan-Draft reconstructs species-representative genome-scale metabolic models from multiple genomes using a pan-reactome-based approach that leverages recurrent genetic evidence to determine the solid core structure of species-level metabolic models.

Key Features:

• Pan-reactome-based approach: Exploits recurrent genetic evidence across multiple genomes to determine the solid core structure of species-level genome-scale metabolic models.
• MAG-specific handling: Addresses incompleteness and contamination of individual metagenome-assembled genomes by comparing MAGs clustered at the species-level.
• Accessory reactions catalog: Generates a catalog of accessory reactions that supports the gapfilling step in metabolic model reconstruction.
• High-quality draft models: Produces high-quality draft genome-scale metabolic models for unculturable species.

Scientific Applications:

• Metabolic modeling of uncultured species: Improves comprehension of metabolic functions of uncultured species by reconstructing accurate genome-scale metabolic models despite incomplete and fragmented genetic information.
• Metagenome-assembled genome analysis: Enables metabolic model reconstruction for unculturable species from incomplete and fragmented metagenome-assembled genomes.
• Species-level metabolic characterization: Creates species-representative metabolic models by integrating genetic evidence across multiple genomes clustered at the species level.

Methodology:

pan-Draft compares metagenome-assembled genomes clustered at the species-level and uses a pan-reactome-based approach exploiting recurrent genetic evidence to determine the solid core structure of species-level genome-scale metabolic models.
