This protease is an active ingredient in laundry detergents, removing protein-comprised dirt in clothes. A significant difference in pressure across the cytoplasmic membrane pushes the cell wall into a specific shape. [6][10] There is evidence that red feathers, with psittacofulvin, are more resistant to degradation.
