PHAST

PHAST identifies and annotates prophage sequences in bacterial genomes to detect prophage regions and assess their integrity and features.


Key Features:

  • Input Flexibility: Accepts raw DNA sequence data and partially annotated GenBank formatted data.
  • Rapid Processing: Processes genomes up to 40 times faster than other prophage identification tools.
  • Enhanced Sensitivity: Demonstrates up to 15% greater sensitivity than comparable tools for prophage detection.
  • Comprehensive Annotation: Performs database comparisons to identify phage features and distinguishes intact and incomplete prophages with detailed component annotations.
  • Quality Assessment: Evaluates "prophage quality" to assess the integrity and completeness of identified prophages.
  • Genomic Visualization: Generates circular and linear genomic visualizations of prophage components.
  • Rich Data Output: Produces annotated tables detailing prophage features and quality assessments.

Scientific Applications:

  • Bacterial genomics: Identifies and annotates prophages to analyze their roles in bacterial evolution.
  • Phage-host interaction studies: Supports analysis of phage-host interactions by localizing prophage sequences and annotating phage genes.
  • Microbial ecology and pathogenicity: Assesses impacts on bacterial pathogenicity and microbial ecology through prophage content and annotations.
  • Lysogeny and induction studies: Distinguishes intact and incomplete prophages to support studies on lysogeny and prophage induction.

Methodology:

Performs database comparisons combined with feature identification steps to locate and annotate prophage sequences.
