Research fields
Antifungal proteins in filamentous fungi
Research on antimicrobial peptides and proteins (AP) is a fast growing scientific field as these biomolecules represent promising candidates for novel drug development. APs have been identified in organisms belonging to most diverse classes. Most of them are active against a broad spectrum of microorganisms, including bacteria, fungi and even viruses. Although the primary amino acid sequence and the protein structure reveals a high diversity, most of these molecules share common structural and functional characteristics. They are small in size, cationic, and they contain 6-8 cysteine-residues which play an important role in protein folding, protein stabilization and antifungal activity.
Our specific interest lies in the identification and characterization of antimicrobial peptides secreted by filamentous fungi (Ascomycota). Most of these antimicrobial peptides/proteins inhibit the growth of plant-, zoo- and human pathogenic moulds, but are inactive against plant and mammalian cells. These findings strongly support their applicability in the prevention and treatment of fungal infection. A prerequisite for future drug development, however, is a detailed knowledge about their structure-function relation and their mode of action which is still not fully understood. In our present studies, we concentrate on the characterization APs that are secreted by the well-known antibiotic producing mould Penicillium chrysogenum. We aim at investigating the mode of action and the structure-function relation and at identifying the AP-specific fungal targets.
