Cartoon representation showing typical modes of diffusion in different environments. For diffusion on the fluid region (lipids in green), the diffusion was generally normal with a diffusion coefficient of 3 μm²/s. Enzymes located near L-DPPC gel domains showed more complex diffusion with, e.g., transient trapping of the enzyme. After extended hydrolysis, areas enriched in hydrolysis product (molecules in olive green and red) showed enzyme diffusion that was significantly slower than on the fluid region. See text for details.
