Cooperative Allosteric Transitions

9.3K
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...

Ladder Diagrams: Complexation Equilibria

668
Ladder diagrams are useful for evaluating equilibria involving metal-ligand complexes. The vertical scale of the ladder diagram represents the concentration of unreacted or free ligand, pL. The horizontal lines on the scale depict the log of stepwise formation constants for metal-ligand complexes and indicate the dominant species in all the regions.
The formation constant, K1, for the formation of Cd(NH3)2+ complex from cadmium and ammonia is 3.55 × 102. Log K1 (i.e. pNH3) is 2.55, and...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

4.2K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Cyclic Processes And Isolated Systems

3.6K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state. 
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

Area of Science:

  • Soft Matter Physics
  • Non-equilibrium Statistical Mechanics
  • Complex Systems

Background:

  • Binary particle systems under external fields can form ordered (laned) or disordered states.
  • Previous research primarily investigated systems with purely repulsive particle interactions.
  • Pattern-forming systems in equilibrium exhibit crystal, stripe, and bubble phases.

Purpose of the Study:

  • To investigate laning transitions in oppositely moving pattern-forming systems with competing attractive and repulsive interactions.
  • To characterize the diverse phases and transitions arising from these competing interactions.
  • To analyze the dynamical behavior and emergent properties of these complex systems.

Main Methods:

  • Simulation of binary particle systems with competing attractive and repulsive interactions under an applied field.
  • Analysis of particle configurations, phase diagrams, and collective dynamics.
  • Examination of velocity-force relationships and differential mobility curves to identify phase transitions.

Main Results:

  • Observed a richer variety of phases compared to purely repulsive systems, including jammed crystals, stripes, and bubbles.
  • Identified novel laned states, including dynamically reordered stripes aligned with the drive and polarized jammed bubble states.
  • Characterized a plastic bubble state and particle hopping between bubbles at higher drives, with distinct signatures in transport properties.

Conclusions:

  • Competing interactions in oppositely driven particle systems lead to significantly more complex phase behavior than repulsive interactions alone.
  • The study reveals diverse jammed and dynamic states, including novel laned configurations and bubble dynamics.
  • Phase transitions are clearly reflected in transport measurements, with stripes exhibiting the lowest unjamming force.
