ISEScan

ISEScan identifies and annotates insertion sequence (IS) elements in prokaryotic genomes to support analysis of genome organization and evolution.

Key Features:

• High sensitivity: Uses profile hidden Markov models (HMMs) constructed from manually curated IS elements to detect IS elements across diverse prokaryotic genomes.
• Comprehensive annotation: Provides an autonomous annotation pipeline that does not depend on pre-existing genome annotations.
• Evaluated performance: Demonstrated superior performance in identifying IS elements when benchmarked against other IS annotation tools using genomes with curated IS annotations.
• Implementation: Implemented in Python.

Scientific Applications:

• Genome organization studies: Produces detailed IS annotations to inform analyses of structural dynamics and evolutionary trajectories in prokaryotic genomes.
• Taxonomic distribution analysis: Enables analysis of the distribution of IS families across taxonomic clades within Archaea and Bacteria, including application to a dataset of 2784 prokaryotic genomes.
• Evolutionary biology research: Supports studies of horizontal gene transfer, genome plasticity, and evolutionary pressures in prokaryotic species.

Methodology:

Detects and annotates IS elements using profile hidden Markov models (HMMs) built from a database of manually curated IS elements.
