Prokka: rapid prokaryotic genome annotation.

Area of Science:

• Genomics
• Bioinformatics

Background:

• Bacterial whole genome sequencing is routine due to advanced DNA sequencing technologies.
• De novo assembly of sequencing reads into contigs is a well-established process.
• Genome annotation remains a bottleneck, with existing methods being slow and unsuitable for sensitive data or computational pipelines.

Purpose of the Study:

• To introduce Prokka, a novel command-line software tool for rapid bacterial genome annotation.
• To provide a solution for efficient and automated annotation of draft bacterial genomes.

Main Methods:

• Prokka is a command-line software tool implemented in Perl.
• It automates the annotation of genomic features on bacterial genome contigs.
• The software is designed for efficient execution on standard desktop computers.

Main Results:

• Prokka can fully annotate a draft bacterial genome in approximately 10 minutes.
• It generates standards-compliant output files.
• The output is suitable for further analysis and visualization in genome browsers.

Conclusions:

• Prokka significantly accelerates the bacterial genome annotation process.
• The tool addresses limitations of existing annotation systems, particularly for sensitive data and computational integration.
• Prokka facilitates routine bacterial genome analysis and downstream applications.
