RHYTHM

RHYTHM predicts buried or exposed residues in helical membrane proteins from primary sequence or structural input to inform residue exposure for structure-function and evolutionary analyses.

Key Features:

• Residue Exposure Prediction: Analyzes primary sequences or secondary/tertiary structural input to predict buried versus exposed residues.
• Structural Calculation: Computes secondary and tertiary structures using a database of precalculated packing files and Pfam-domain evolutionary insights.
• Dual-Matrix Approach: Employs class-specific matrices for channels and membrane-coils to enhance residue exposure accuracy.
• Output Details: Provides secondary structure, topology, residue contact type, and evolutionary conservation status.

Scientific Applications:

• Membrane Protein Analysis: Supports studies of structure-function relationships, drug design, structural biology, and evolutionary conservation in helical membrane proteins.

Methodology:

Calculates secondary and tertiary structures using a database of packing files and Pfam-domain evolutionary patterns. Applies dual-matrix models for channels and membrane-coils to refine residue exposure predictions.
