Water dynamics near an enzyme-collagen complex: The rates at which water molecules exchange hydrogen bonds with one another depend on the distance from the active site of the enzyme (gray) and on the type of collagen interacting with the enzyme; the different rates create a gradient of water motions, ranging from extremely fast (red) to very slow (blue and light-blue)
