Probcons WS (jabaws)

Probcons WS (jabaws) performs progressive protein multiple sequence alignment using probabilistic consistency methods to produce accurate alignments for downstream analyses such as phylogenetic inference and molecular modeling.

Key Features:

• Multiple Sequence Alignment Methods: Implements five MSA algorithms: ProbCons, T-Coffee, Muscle, Mafft, and ClustalW.
• JABAWS framework: Operates within the JABAWS (Java Archive of Bioinformatics Web Services) framework.
• Probabilistic consistency: Applies probabilistic consistency scoring in a progressive alignment strategy to enhance alignment accuracy.
• Parameter Customization: Exposes per-application alignment parameters and supports administrator-defined named parameter presets and execution limits via configuration files.

Scientific Applications:

• Evolutionary biology: Produces alignments used for inference of evolutionary relationships and comparative sequence analyses.
• Protein structure prediction: Provides aligned homologous sequences that inform comparative and template-based structure modeling.
• Functional annotation: Supports identification of conserved residues and motifs for gene and protein function annotation.
• Comparative genomics: Enables sequence comparison across species for conserved region and synteny analyses.
• Phylogenetic inference: Supplies high-quality multiple sequence alignments required for tree reconstruction and evolutionary modeling.
• Molecular modeling: Supplies sequence alignments that inform molecular modeling and structural interpretation of proteins.

Methodology:

Uses a progressive alignment strategy based on probabilistic consistency models to compute consistent protein multiple sequence alignments.
