Mini review on the structure and supramolecular assembly of VDAC

Abstract

The Voltage Dependent Anion Channel (VDAC) is the most abundant protein in the outer membrane of mitochondria. This strategic localization puts it at the heart of a great number of phenomena. Its recent implication in apoptosis is an example of the major importance of this protein and has created a surge of interest in VDAC. There is no atomic-resolution structure allowing a better understanding of the function of VDAC, so alternative techniques to X-ray diffraction have been used to study VDAC. Here we discuss structural models from folding predictions and review data acquired by Atomic Force Microscopy (AFM) imaging that allowed to observe VDAC's structure and supramolecular organization in the mitochondrial outer membrane. © 2008 Springer Science+Business Media, LLC.

Supramolecular chemistry

Supramolecular chemistry refers to the branch of chemistry concerning chemical systems composed of a discrete number of molecules. The strength of the forces responsible for spatial organization of the system range from weak intermolecular forces, electrostatic charge, or hydrogen bonding to strong covalent bonding, provided that the electronic coupling strength remains small relative to the energy parameters of the component.

Molecular self-assembly

In chemistry and materials science, molecular self-assembly is the process by which molecules adopt a defined arrangement without guidance or management from an outside source. There are two types of self-assembly: intermolecular and intramolecular. Commonly, the term molecular self-assembly refers to the former, while the latter is more commonly called folding. Molecular self-assembly is a key concept in supramolecular chemistry. This is because assembly of molecules in such systems is directed through non-covalent interactions (e.

X-ray crystallography

X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information.
