Plant Enzymes (IMAGE) Cornell University Caption This schematic diagram shows the newly discovered class of plant enzymes with a cellulose-binding module (shown in blue), sticking to a plant cell wall. The binding module of the enzyme helps the catalytic region of the enzyme (shown in more detail in gray in the pullout part of the picture) break down the crystalline cellulose.
