GenomePartitioner

GenomePartitioner partitions large-scale DNA constructs into fabricable DNA blocks and optimizes flanking homologies to support assembly of genome-scale constructs for synthetic biology.

Key Features:

• Multi-Level Partitioning: Automated fragmentation of extensive DNA sequences into hierarchical, manageable segments with generation of optimal retrosynthetic routes for higher-order DNA assembly.
• Flanking Homologies Optimization: Optimization of overlapping homology regions between adjacent blocks with removal of hairpins, sequence repeats, and problematic sequence patterns to improve in vitro and in vivo assembly compatibility.
• Automated Pipeline: A fully automated computational pipeline that performs sequence partitioning and homology optimization for downstream assembly planning.
• Validation and Effectiveness: Demonstrated by partitioning a 783 kb Caulobacter crescentus genome design and enabling successful assembly of a 20 kb test segment from 1 kb subblocks, supporting reductions in synthesis cost and timelines.
• Broad Applicability: Translates complex DNA designs into sequences compatible with standardized ordering and assembly protocols for synthetic biology projects exploiting microbial genome diversity.

Scientific Applications:

• Genome-scale construct design: Partitioning and homology optimization for design and assembly of genome-scale DNA constructs, including large bacterial genomes such as Caulobacter crescentus (783 kb).
• Assembly route planning and validation: Generation of retrosynthetic assembly plans and experimental validation, exemplified by assembly of a 20 kb segment from 1 kb subblocks.
• Synthetic biology and microbial genome engineering: Enabling translation of complex microbial genome designs into sequences compatible with standardized assembly workflows to reduce synthesis costs and timelines.

Methodology:

An automated pipeline fragments input DNA into smaller blocks, optimizes overlapping flanking homologies, eliminates hairpins, repeats and problematic patterns, and generates optimal retrosynthetic routes for higher-order assembly.
