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 analyses the...

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 polypeptide...

Ligand Binding Sites

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Protein Folding Quality Check in the RER

Protein Folding Quality Check in the RER

ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

The Equilibrium Binding Constant and Binding Strength

The Equilibrium Binding Constant and Binding Strength

The equilibrium binding constant (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

Background:

Protein-protein docking is crucial for understanding biological processes.
Accurate prediction of protein complex structures is computationally challenging.
Initial docking methods generate numerous false positives requiring efficient rescoring.

Purpose of the Study:

To develop and validate a novel scoring function for protein-protein docking.
To improve the discrimination of correct protein complex predictions.
To enhance the efficiency of computational protein docking pipelines.

Main Methods:

Developed a scoring function (ZRANK) incorporating electrostatics, van der Waals, and desolvation terms.
Optimized scoring term weights using a set of test cases.
Validated the optimized function on an independent, nonredundant dataset.
Compared ZRANK performance against initial ZDOCK rankings.

Main Results:

ZRANK significantly improved the success rate of protein-protein docking predictions compared to ZDOCK.
The number of top-ranked correct predictions (No. 1 hits) increased substantially across different ZDOCK versions.
ZRANK demonstrated robust performance on a large benchmark dataset.

Conclusions:

ZRANK is an effective scoring function for rescoring protein-protein docking predictions.
It can be used as a standalone refinement protocol or as a preprocessing step.
ZRANK enhances the identification of biologically relevant protein complexes.
