If I remember correctly from my undergraduate studies, subtilisin is one
example where an engineered protein has "left the lab".  This enzyme is used in
many of the enzymatic washing powders, and was made more stable by adding extra
cys residues to increase the number of intramolecular cys-cys bridges.  Don't
have any refs, sorry!
