Protein Complex Assembly

Protein Complex Assembly

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.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Valence Bond Theory

Valence Bond Theory

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Coordination Number and Geometry

Coordination Number and Geometry

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Temperature Dependent Deformation

Temperature Dependent Deformation

In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...

Cooperative Allosteric Transitions

Cooperative Allosteric Transitions

Cooperative Allosteric Transitions

Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Area of Science:

Materials Science
Supramolecular Chemistry

Background:

Coordination-driven self-assemblies typically lack thermal responsiveness.
Perylene derivatives often form micro-belt structures through self-assembly.

Purpose of the Study:

To investigate temperature-dependent structural transitions in coordination-driven self-assemblies.
To explore the design of novel temperature-responsive soft materials.

Main Methods:

Synthesis of self-assemblies using perylene tetracarboxylate and metal ions.
Temperature-controlled structural analysis of the resulting materials.

Main Results:

A unique pinecone structure was observed upon increasing temperature.
The structural transition is attributed to a switch from intermolecular to intramolecular coordination.
This switch disrupts inter-perylene connections, altering assembly morphology.

Conclusions:

Demonstrated a strategy to achieve thermal responsiveness in coordination self-assemblies.
The findings may inspire the development of controllable, temperature-dependent soft materials.
