Conserved Binding Sites

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Conservation of Protein Domains Over Different Proteins

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain. Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Point and Frameshift Mutations

Point and Frameshift Mutations

Point mutations are genetic alterations involving the change of a single nucleotide base pair in DNA. Depending on how the alteration affects protein synthesis, they can lead to various consequences.Point mutations fall into the following types:Silent mutations occur when a nucleotide change does not alter the amino acid sequence due to the redundancy of the genetic code. For instance, changing ACC to ACA still encodes threonine, leaving the protein function unaffected. This occurs because...

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Background:

Predicting the functional impact of protein mutations is crucial for understanding disease and protein engineering.
Existing tools often lack the flexibility to handle diverse structural data or large-scale analyses.

Purpose of the Study:

To introduce AUTO-MUTE 2.0, an enhanced stand-alone software package for predicting functional consequences of single amino acid substitutions.
To provide improved predictors for protein stability, activity changes, and disease potential of mutations.

Main Methods:

Utilizes a combination of structure-based features and trained statistical learning models.
Incorporates five distinct prediction tools: three for stability, one for activity, and one for disease potential.
Rewritten and updated codebase with new features based on user feedback.

Main Results:

The software predicts changes in protein stability, activity, and disease association for single residue substitutions.
New features include batch job processing for large datasets, support for modified/custom protein structures (PDB), and utilization of NMR multi-model files.
The command-line tools complement the existing AUTO-MUTE web server.

Conclusions:

AUTO-MUTE 2.0 offers a powerful and flexible platform for analyzing the functional impact of protein mutations.
The enhanced capabilities facilitate large-scale studies and the use of diverse structural data in mutation effect prediction.
