RevTrans

RevTrans translates DNA sequences into peptides, aligns the peptides using a BLOSUM-62 substitution matrix, and reverse-translates the alignment to produce codon-aware DNA alignments.

Key Features:

• Virtual Translation: Converts DNA sequences into peptide (amino acid) sequences for alignment.
• Peptide Sequence Alignment: Aligns peptide sequences using the BLOSUM-62 substitution matrix.
• Reverse Translation: Reconstructs DNA alignments from peptide alignments while preserving codon integrity and codon-aligned gaps.

Scientific Applications:

• Phylogenetic Analysis: Produces codon-aware DNA alignments that improve accuracy for evolutionary and phylogenetic studies.

Methodology:

Translates DNA to peptides, aligns peptides using BLOSUM-62 substitution matrices, and reverse-translates to DNA while maintaining codon groupings.
