===Function===
 +
The enzyme was designed in order to deal with the problem of drug overdosing, by administering an enzyme with a high catalysis rate into the bloodstream of patients who are overdosing, the effects can be rapidly reduced, however the problem posed by the usage of naturally occurring CocE is its lack of thermal stability (half life at 37°C = ~12mins), so by changing the bonding of the protein chain a more thermally stable version of the enzyme was created, thereby increasing its potential for <i>in vivo</i> usage, thus the current trials it is undergoing.

Cocaine Esterase mutant enzyme (E172-173)

The mutant enzyme of part (part:BBa_K3588001). It is able to breakdown cocaine, as well as benzoylecogonine, through hydrolysis into benzoate and ecgonine methyl ester. With a dramatically increased in vitro half life from the wildtype enzyme it is currently in phase II trials as a cocaine overdose treatment,[1] though in our project we were intending to use it to breakdown cocaine in the sewers.
