Protein–lipid interaction is the influence of membrane proteins on the lipid physical state or vice versa.. The questions which are relevant to understanding of the structure and function of the membrane are: 1) Do intrinsic membrane proteins bind tightly to lipids (see annular lipid shell), and what is the nature of the layer of lipids adjacent to the protein?
The simulations done my PIMD can broadly characterize the biomolecular systems, covering the entire structure and organization of the membrane, including the permeability, protein-lipid interactions, along with "lipid-drug interactions, protein–ligand interactions, and protein structure and dynamics."
Significance of research: All experiments are carried out at 60 °C. [4] Changes in the equilibrium constant (K) are used to determine what type of lipid interactions are occurring within the modeled membrane as well as observe liquid-ordered versus liquid-disorder regions. [4]
Critical Assessment of PRediction of Interactions (CAPRI) is a community-wide experiment in modelling the molecular structure of protein complexes, otherwise known as protein–protein docking. The CAPRI [ 1 ] is an ongoing series of events in which researchers throughout the community attempt to dock the same proteins, as provided by the ...
Protein–protein interactions (PPIs) are physical contacts of high specificity established between two or more protein molecules as a result of biochemical events steered by interactions that include electrostatic forces, hydrogen bonding and the hydrophobic effect. Many are physical contacts with molecular associations between chains that ...
The challenge in predicting protein structures is that there lacks a physical model that can fully predict protein tertiary structures from their amino acid sequence. This problem is known as the de novo protein structure prediction problem and is one of the great problems of modern science. [ 20 ]
A binding interaction between a small molecule ligand and an enzyme protein may result in activation or inhibition of the enzyme. If the protein is a receptor, ligand binding may result in agonism or antagonism. Docking is most commonly used in the field of drug design — most drugs are small organic molecules, and docking may be applied to:
The proteolipid code relies on the concept of a zone, which is a functional region of membrane that is assembled and stabilized with both protein and lipid dependency. Integral and lipid-anchored proteins are proposed to form three types of zones: proteins with an associated lipid fingerprint, [9] protein islands, and lipid-only voids. Although ...
