Aggrescan4D

Aggrescan4D predicts pH-dependent protein aggregation and engineers protein solubility using structure-informed analysis and evolutionary-informed mutation protocols.

Key Features:

• pH-Dependent Aggregation Prediction: Predicts the pH-dependent aggregation of protein structures.
• Evolutionary-Informed Mutation Protocol: Automatically engineers protein solubility without compromising structure and stability using evolutionary information.
• Precalculated Results Integration: Integrates precalculated results for nearly 500,000 jobs from the A3D Model Organisms Database.
• AlphaFold Structure Retrieval: Retrieves structures from the AlphaFold database.

Scientific Applications:

• Protein Aggregation Analysis: Analyzes and predicts pH-dependent protein aggregation propensities from structural data.
• Protein Solubility Engineering: Designs mutations to improve protein solubility while preserving structural integrity and stability.
• Aggregation-Related Disease Research: Supports understanding of protein aggregation mechanisms relevant to disease genesis and drug discovery constraints.
• Industrial Protein Production: Assists in addressing aggregation challenges in industrial protein production and formulation.

Methodology:

Aggrescan4D builds on the A3D method and extends it with pH-dependent aggregation prediction and evolutionary-informed automatic mutation protocols.
