Metal-dependent fungal enzyme (None (no widely-accepted universal abbreviation for the collective class of metal-dependent fungal enzymes; individual enzymes may have abbreviations, e.g., "LiP" for lignin peroxidase))

Metal-dependent fungal enzymes are a broad group of enzymes produced by fungi that require metal ions—most commonly iron, copper, zinc, or manganese—for their structural integrity or catalytic activity. They encompass diverse enzyme classes, including oxidoreductases (e.g., laccases, peroxidases), hydrolases (e.g., metalloproteases, amy-lases), and other metalloenzymes. These enzymes are central to fungal physiology and pathogenesis: they facilitate nutrient acquisition, degradation of host tissues, and protection against oxidative stress, and are crucial in processes such as lignin degradation, virulence factor expression, and environmental adaptation. Because many of these pathways are unique or critical to fungal survival, metal-dependent enzymes are explored as antifungal drug targets, though their widespread biological roles (including analogs in humans) present notable safety and selectivity challenges[2][3][4]. For greater specificity and structured information, individual enzyme names or families (e.g., "Fungal laccase," "Fungal metalloprotease") are preferred over this generic category.

Metal chelation: Sequester essential metals (iron, copper, zinc) so fungal enzymes cannot function. Enzyme inhibition: Small molecules inhibit active sites of metal-dependent enzymes (inhibiting proteases, laccases, peroxidases, etc.). Nutritional immunity modulation: Enhance host’s sequestration of metals to starve fungus.
