Scratch Protein Predictor

Scratch Protein Predictor predicts tertiary protein structures and multiple residue-level structural features from amino acid sequences to provide insights into protein architecture.

Key Features:

• Secondary Structure Prediction: Predicts alpha-helices, beta-sheets, and random coils from amino acid sequence.
• Relative Solvent Accessibility: Estimates residue exposure to solvent to inform interaction and functional analyses.
• Disordered Regions Identification: Identifies regions that lack a fixed three-dimensional structure indicative of intrinsic disorder.
• Domain Prediction: Delineates distinct structural domains within protein sequences.
• Disulfide Bridge Prediction: Predicts presence and locations of disulfide bonds between cysteine residues.
• Single Mutation Stability Analysis: Assesses how single amino acid substitutions affect protein stability.
• Residue Contacts Prediction: Predicts residue–residue contacts, including comparisons to average contact values and individual contact predictions.

Scientific Applications:

• Structural Biology: Supports hypothesis generation for three-dimensional protein conformations from sequence data.
• Protein Engineering: Informs design and evaluation of mutations through predicted stability and structural features.
• Drug Discovery: Provides solvent accessibility and disorder information relevant to target characterization and ligand design.
• Functional Genomics: Uses domain and structural predictions to aid functional annotation and evolutionary analyses.

Methodology:

Computational algorithms analyze submitted amino acid sequences to generate predictions for the user-selected structural features.
