Nutrient Excess Triggers the Expression of the Antifungal Protein PAFB.

Nutrient limitation and nonfavorable growth conditions have been suggested to be major triggers for the expression of small, cysteine-rich antimicrobial proteins (AMPs) of fungal origin, e.g., the antifungal protein (PAF), the antifungal protein (AFP), the antifungal protein (AnAFP).
