In the proposed project we will investigate and extract sequence features of lipid membrane-lytic peptides. The study integrates both computational and biochemical experiments. We introduce the concept of "peptide-morphing" as a means for the systematic analysis and generation of structure-activity relationship models. The morphing process allows for physicochemically-motivated quasi-continuous sequence transitions which we will monitor by biophysical measurements. The gathered experimental data serves as guidance for the subsequent de novo peptide design with modulated membrane activity and defined biophysical properties. The research project is structured in three tiers, the i) computational design and biophysical/biochemical characterization of antimicrobial peptides and their morphed derivatives, ii) investigation of the property patterns that are responsible for the mechanisms of action of cationic helical antimicrobial peptides, and iii) development and implementation of software algorithms for length-invariant de novo design of peptides with the desired activity spectra. The project will result in profound insights into the biophysical nature of peptide-membrane interaction and help elicit the causative amino acid sequence patterns. From the perspective of applied research, the projects addresses the pressing need for new antibacterial molecular agents by translating these insights into an original algorithm for the rational design of membrane-active peptides with modulated levels of activity.
