Purpose & Contents
Antimicrobial resistance threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi. In order to eliminate or substantially reduce the extent of bacterial attachment and biofilm formation on surfaces, intensive efforts have been focused on the fabrication of new surfaces, or on the improvement of the performance of existing antibacterial surfaces. However, there is no perfect candidates for antimicrobial coating agents. The purpose of research is to develop novel antimicrobial and antiviral biomaterials to protect biomedical devices and household items from cellular infection.
Results
Adhesive antimicrobial/antiviral peptides, one candidate of strong antimicrobial coating agents, will be developed in this study as follows:
A. Development of novel adhesive antimicrobial peptides
-design and synthesis of antimicrobial peptides and adhesive domain
-surface binding activity analysis of the fusion peptides
-antimicrobial activity analysis
B. Development of antimicrobial peptide expression system
-novel toxic protein/peptide expression system development
-design of novel fusion partners to block the harmful effect of cationic peptides
-improvement of 2-cistronic peptide expression system
C. Development of unnatural amino acid incorporation system
-production of non-cannonical amino acid (NCAA) in bacteria
-mutation and screening of tRNA synthetase for NCAA incorporation
D. Mass production of adhesive antimicrobial/antiviral peptides
-construction of novel microbial cell factory for the production of peptides
-process optimization of the antimcirobial peptide production
E. Characterization of the produced coating peptides
-analysis of the binding activity of the adhesive peptides on the surface
-single-layer and multiple layers spreading method development
-coating the surface of the medical devices and household items In this study, we will develop novel antimicrobial and antiviral coating peptides by fusion of peptides with adhesive domain of mussel foot proteins.
And it will be coated on the surface on electrical devices, household items, and medical devices to protect them from the bacterial infection. Final performance goal of this study is 4 journal publications, 1 patents pending, and 1 patents publication.
Expected Contribution
Outcomes of research will be expected to provide the solution of bacterial infection problem by coating antibacterial and antiviral materials on the surface of medical devices , daily household items, and electric devices. The research will also provide techniques regarding production and in vivo delivery of various therapeutic peptides/proteins and activate researches on synthetic biology in Korea.
