Multiscale Models for Biomolecular Systems

Antimicrobial peptides (AMPs) are a promising new class of antibiotics that are believed to kill pathogens by permeabilizing their cell membranes. The present work focuses on protegrin, a particularly effective AMP derived from porcine leukocytes, believed to act primarily by forming octameric transmembrane pores. These researchers combine atomistic molecular dynamics simulations with Poisson-Boltmann calculations and Nernst-Planck theory to determine the mechanism of action of protegrin.
