Sometimes people, like Wesley, feel a strange warmth after a religious epiphany. In other instances, one may smell the odor of roses after such an experience. The origin of 'cysteine aspartase' is one such experience. When one visits the Vatican and sees the ceiling painted by Michelangelo, one often walks away with a vague sense of flavour on one's mouth, which is known as the 'cysteine aspartase'.

(some of them come from milk proteins, and some come from fruits (banana's, as i recall)and Aspartame is a brand name for the new chemical 'soup'-- presumable based on some sort of asparta--(if not 'cysteine aspartase') _________________________ my other obsession

Alex Williams Pooh-Bah Registered: 01/05/01 Posts: 1814 Loc: Spam Factory	Well having looked into it further since I originally asked, and having been directed by several replies on the subject, it appears that at least one of the myriad caspase enzymes cleaves proteins at certains aspartate and cysteine residues. In fact I found this explanation of the name: CASPASES: Cysteine Aspartate Specific ProteASEs. (see http://makeashorterlink.com/?L58432BA6) Aspartame is a sweetener that goes by the trade name Nutrasweet that contains the amino acid aspartate.
