MUTATIONEXPLORER- A WEBSERVER FOR MUTATION OF PROTEINS AND 3D VISUALIZATION OF ENERGETIC IMPACTS.

Area of Science:

• Biochemistry and Structural Biology
• Bioinformatics and Computational Biology

Background:

• Understanding protein stability and function requires analyzing mutations within their three-dimensional (3D) structural context.
• Computational tools are essential for mapping sequence variations onto protein structures to predict functional impacts.

Approach:

• The MutationExplorer webserver provides a platform for users to input sequence changes and visualize their effects on protein 3D models.
• It dynamically updates the 3D structure as variants are entered, highlighting estimated energy changes.
• Supports per-residue input, full sequence replacement for back-mutation of PDB structures, and human single nucleotide polymorphisms (SNPs) via VCF format.

Key Points:

• MutationExplorer integrates sequence variation analysis with protein structural visualization.
• It offers intuitive input methods, including direct sequence changes and VCF files for SNPs.
• Enables rapid assessment of mutation impacts on protein structure and energetics.

Conclusions:

• MutationExplorer facilitates the study of protein variation by linking sequence data to structural models.
• The webserver democratizes the analysis of mutation effects, previously limited to desktop applications.
• It serves as a valuable resource for researchers investigating protein function and disease-related genetic variations.
