TRDistiller

TRDistiller filters protein sequences to identify and enrich candidates containing tandem repeats (TRs) for large-scale proteome analysis.

Key Features:

• Rapid Filtering Mechanism: Compares composition and order of short strings in adjacent sequence motifs to distinguish TR-containing sequences from non-TR sequences.
• Efficiency and Sensitivity: Retains 99.2% of TR-containing sequences while discarding up to 22.5% of proteins lacking tandem repeats.
• Time Efficiency: Provides a rapid solution suitable for extensive proteome datasets compared with other sensitive algorithms that are time-consuming.

Scientific Applications:

• Proteome Analysis: Filters out non-TR proteins to reduce dataset size and prioritize sequences for subsequent tandem-repeat detection methods.
• Structural Biology Research: Identifies proteins with periodic sequences that may fold into elongated fibrous structures, supporting study of protein structure–function relationships.

Methodology:

Performs comparative analysis of the composition and order of short adjacent sequence motifs to differentiate sequences with and without tandem repeats, thereby reducing computational load during initial dataset screening.
