[Evaluation of bilayer distortion parameters in the vicintiy of membrane proteins on the basis of an elastic model]

On the basis of elastic three-layer model of a biomembrane and taking into consideration the surface tension forces the shape of the distortion zone near a macromolecule put into the bilayer is calculated. The dimensions of the zone are about the membrane thickness and vary from 1 up to 5 nm when the elastic moduli are varied. The distortion zone energy is estimated for different macromolecule dimensions and values of the border angle on the macromolecule surface, its values may reach about tens of kT.
