Abstract

Insights

A novel cell wall protein, EF0737, from Enterococcus faecalis was cloned and expressed. This protein interacts with fibrinogen, mucin, and patient sera, suggesting its role in E. faecalis infections.

Area of Science:

  • Microbiology
  • Molecular Biology
  • Immunology

Background:

  • Enterococcus faecalis is a leading cause of human infections.
  • Pathogenic E. faecalis utilizes surface components for adhesion and immune response induction.
  • EF0737 is a novel cell wall associated protein potentially involved in E. faecalis pathogenesis.

Purpose of the Study:

  • To clone and express the EF0737 protein.
  • To investigate the interaction of EF0737 with plasma proteins and patient sera.

Main Methods:

  • Cloning of the ef0737 gene into expression vectors.
  • Expression and purification of recombinant EF0737 in E. coli.
  • Western blot analysis to detect protein interactions.

Main Results:

  • Successful cloning and expression of EF0737 in E. coli.
  • EF0737 demonstrated binding to fibrinogen and mucin.
  • EF0737 reacted with sera from patients with E. faecalis infections.

Conclusions:

  • EF0737's interactions suggest a role in E. faecalis pathogenesis.
  • Further characterization of EF0737 is needed to understand host-pathogen interactions.

Factors Affecting Protein-Drug Binding: Protein-Related Factors

Drug binding to proteins is a key aspect of pharmacokinetics and can influence a drug's distribution, absorption, and elimination in the body. Several factors, including the drug's physiochemical properties, protein concentration, disease states, and the number of binding sites on the protein, influence this process.
The physicochemical properties of a drug play a significant role in its ability to bind to proteins. Lipophilic drugs, which dissolve in fats, oils, and lipids, can be...

The Equilibrium Binding Constant and Binding Strength

The equilibrium binding constant (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

Drug Distribution: Plasma Protein Binding01:29

Drug Distribution: Plasma Protein Binding

Drugs predominantly attach to plasma proteins, with only a small percentage remaining unbound. The unbound portion can be calculated as one minus the bound fraction. Acidic drugs form large, inactive complexes by reversibly binding to plasma albumin, which prevents them from diffusing across biological barriers. These drug-protein complexes act as reservoirs for the drugs. As the concentration of unbound drugs decreases, these complexes quickly dissociate to release the free drug, maintaining...

Protein-Drug Binding: Determination Methods

Determining protein-drug binding can be achieved through indirect and direct methods, each providing valuable insights into the interaction between proteins and drugs.
Indirect methods involve isolating the bound drug from its free form in biological samples such as blood, serum, or plasma. These techniques aim to measure the percentage of drugs bound to proteins. Equilibrium dialysis is a commonly used method where the free drug concentration at equilibrium is measured by separating the bound...

Ligand Binding and Linkage00:49

Ligand Binding and Linkage

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...

Ligand Binding Sites02:40

Ligand Binding Sites

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...
