ARB

ARB organizes and analyzes nucleic acid and amino acid sequence data to support sequence database management, processed sequence alignments, phylogenetic tree analysis, structure editing, profile/filter calculation, and hybridization probe design for ribosomal RNA and related molecular studies.

Key Features:

• Data Management: A central database stores processed sequence alignments and linked descriptive data, supports import and export of sequences, and can be organized by phylogenetic relationships or other user-defined criteria across local or global networks.
• Sequence Alignment: Tools for aligning primary structures of nucleic acid and amino acid sequences to enable comparative analyses.
• Structure Editing: Capabilities for editing primary and secondary sequence structures and associated annotations.
• Phylogenetic Analysis: Visualization and analysis of phylogenetic trees integrated with sequence data and database organization.
• Profile and Filter Calculation: Calculation of profiles and filters to support sequence comparison and identification.
• Hybridization Probe Design: Design and evaluation of specific hybridization probes for targeted molecular studies.
• Comprehensive Data Analysis Tools: Additional components for diverse bioinformatics data analysis tasks beyond alignment and phylogeny.

Scientific Applications:

• Ribosomal RNA analysis: Processing, alignment, and comparative analysis of ribosomal RNA sequences.
• Nucleic acid and amino acid sequence analysis: Management and analysis of primary and secondary structures for nucleic acids and proteins.
• Phylogenetic inference and database organization: Construction, visualization, and analysis of phylogenetic trees and organization of sequence databases by phylogeny.
• Hybridization probe design and evaluation: Design and assessment of probes for targeted molecular experiments.
• Sequence database management and comparative analyses: Import/export and linked-data management to support comparative analyses across datasets.

Methodology:

Computational steps include storage of processed sequence alignments in a central database, sequence import/export, primary-structure alignment, primary and secondary structure editing, phylogenetic tree visualization and analysis, profile and filter calculation, hybridization probe design and evaluation, and database organization by phylogenetic or user-defined criteria.
