Protein-protein Interfaces02:04

Protein-protein Interfaces

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...

Mechanisms of Membrane Domain Formation00:59

Mechanisms of Membrane Domain Formation

3.2K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with...

Fluid Mosaic Model

14.6K
Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

937
Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the...

Theories of Dissolution: Diffusion Layer Model

2.1K
Dissolution, the process by which drug particles dissolve in a solvent, is explained by the diffusion layer model, a theoretical framework that simulates the absorption of oral drugs and allows us to analyze experimental data.
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...

  • Biomaterials

Background:

  • Protein behavior at solid-liquid interfaces is crucial across various scientific fields.
  • Environmental conditions significantly influence microscopic protein dynamics (adsorption, aggregation) and macroscopic properties (surface coverage, structure).

Purpose of the Study:

  • To propose a novel bottom-up approach for studying interfacial protein behavior.
  • To overcome limitations of traditional top-down modeling in connecting environmental factors to protein dynamics.
  • To guide rational design for desirable protein behaviors at interfaces.

Main Methods:

  • Direct observation of microscopic protein dynamics using single-molecule tracking.
  • Development and application of complex models that incorporate detailed microscopic data.
  • Extrapolation of single-molecule observations to the macro-scale using computational modeling.

Main Results:

  • The bottom-up approach allows direct measurement of microscopic protein dynamics.
  • Complex models can be parameterized by experimental microscopic data.
  • Macroscopic predictions generated from bottom-up models can be compared with experimental observations.

Conclusions:

  • The proposed bottom-up approach offers a more accurate way to understand interfacial protein behavior.
  • This method facilitates a stronger connection between environmental conditions and macroscopic protein properties.
  • It provides a framework for rational design in applications involving protein-surface interactions.
