HyperEx

HyperEx extracts hypervariable regions from 16S ribosomal RNA (rRNA) gene sequences to enable precise taxonomic identification and comparative analysis of bacteria and archaea.

Key Features:

• Primer-Based Extraction: Extracts specific hypervariable regions using embedded primers or user-defined primers to target chosen 16S rRNA regions.
• Algorithmic Precision: Employs the Myers algorithm for exact pairwise sequence alignment to identify primer matches and delimiting regions.
• Sequence Scope: Operates on complete or near-complete 16S rRNA sequences to retrieve target hypervariable regions.
• Metabarcoding Support: Targets hypervariable regions commonly used in high-throughput metabarcoding and microbial community analyses.

Scientific Applications:

• Phylogenetic analysis: Enables phylogenetic studies and taxonomic classification of bacteria and archaea using 16S rRNA hypervariable regions.
• Metabarcoding and community profiling: Facilitates high-throughput metabarcoding workflows for assessing microbial diversity and community structure.
• Region selection for taxonomic resolution: Supports selection of hypervariable regions according to their differing taxonomic resolution for study-specific objectives.

Methodology:

Performs in silico extraction of hypervariable regions from complete or near-complete 16S rRNA sequences using embedded or user-provided primers and exact pairwise alignment via the Myers algorithm to identify primer matches and extract regions.
