Fluorinated aminoacids: Trifluoroselenomethionine, a new unnatural aminoacid, shows enhanced methioninase‐induced cytotoxicity, relative to selenomethionine, toward human colon cancer cells. Surprisingly, E. coli given 9:1 trifluoroselenomethionine/methionine mainly afford proteins containing selenomethionine units. The removal of the trifluoromethyl group in E. coli is enzymatically catalyzed.
