Summary
We developed GoCa, a computational model to simulate how large protein complexes assemble. This structure-based model accounts for folding and binding, enabling the study of complex formation dynamics.
Area of Science:
- Structural biology
- Computational biology
- Biophysics
Background:
- Biological functions rely on large protein complexes.
- Advances in structure determination and prediction have increased solved multiprotein assemblies.
- The assembly process of these large complexes remains poorly understood.
Purpose of the Study:
- To introduce GoCa, a rapid computational structure-based model for simulating multiprotein complex assembly.
- To enable the study of the dynamics of complex formation based on known native structures.
Main Methods:
- Developed a structure-based (SB) model named GoCa.
- Incorporated distinctions between intra- and intersubunit interactions to model coupled folding and binding.
- Enabled automatic handling of identical subunit permutations and multiple native structures for proteins with global transitions.
Main Results:
- Successfully tested the GoCa model on various multiprotein complexes.
- Demonstrated the model's capability to follow the assembly process of large complexes.
- Provided publicly available source code and a web server for generating input files.
Conclusions:
- GoCa offers a novel approach to studying the assembly pathways of large protein complexes.
- The model advances our understanding of how complex biological machinery is constructed.
- Accessibility through GitHub and a web server facilitates broader research application.

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...

01:24Protein Organization
6.5K
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.

12.5K
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...

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...

00:49Ligand Binding and Linkage
4.8K
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

02:41Protein Complex Assembly
10.6K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
