Title: Biochemical; Protein Purification Challenge
Description: The sheath (in green at top), with the desired protein linked to it (in yellow at right), first sticks to the engineered enzyme (in blue at bottom left) - allowing impurities and other proteins to be washed away. Then an infusion of fluoride acts as a trigger, causing the enzyme to cut away the desired protein (at the point where the sheath and protein connect), which can be collected in a pure state. The sheath can then be washed away and the process repeated.
