I don't have an enzyme
I have the dog. If the alarm clock doesn't do it's job, then having a dog leap on the bed, step on your genitals and proceed to lick your face generally does the trick just as well.
Although, presumably he has this enzyme because he does it to me every morning at the same time. Am waiting for scientists to discover how to tell this enzyme that it's the weekend and there's no need to go fro a walk for at least another 2 hours...
