ClustalW (BioLib)

ClustalW (BioLib) performs multiple sequence alignment of DNA and protein sequences to identify conserved regions and support evolutionary and functional analyses.

Key Features:

• Rewritten in C++: The codebase was rewritten in C++ to improve performance and enable further algorithmic development.
• Alignment algorithms: Implements advanced alignment algorithms that were optimized during the C++ rewrite.
• Progressive alignment: Uses progressive alignment techniques that construct multiple sequence alignments by combining pairwise alignments.
• Scalability: Optimized to handle large datasets efficiently.

Scientific Applications:

• Conserved region identification: Aligns sequences from different species or within gene families to reveal conserved residues relevant to structure or function in genomics and proteomics.
• Evolutionary analysis: Compares homologous sequences to inform phylogenetic analyses and study sequence evolution.
• Functional prediction: Uses similarity to known proteins or genes to support inference of unknown protein or gene function.

Methodology:

Employs advanced alignment algorithms optimized in a C++ rewrite and uses progressive alignment techniques that build multiple sequence alignments by combining pairwise alignments, with optimizations for large datasets.
