Physical Understanding Of Pore Formation On Supported Lipid Bilayer By Bacterial Toxins

摘要

Pore forming toxins are being classified in the protein community based on their ability of forming pores in living cell membranes. Some initial study has apparently pointed out the crystallographic pathway rather can be viewed as a structural as well as morphological changes of proteins in terms of self assembly before and during the pore formation process in surfactant medium. Being a water soluble compound, it changes its conformation and originates some pre-pore complex, which later partially goes inside the cell membrane causing a pore. The physical mechanism for this whole process is still unknown. In this study we have tried to understand these types of biological processes from physical point of view by using supported lipid bilayer as a model system.
