SELENOMETHIONINE

'Selenomethionine' is an amino acid containing selenium. The L-isomer of selenomethionine, known as Se-met, is a common natural food source of selenium. It can not be synthesized by higher animals, but can be obtained from plant material.
Incorporation of Selenomethionine into proteins in place of Methionine aids the structure elucidation of proteins by X-ray crystallography using multi-wavelength anomalous diffraction (MAD). The incorporation of heavy atoms such as Selenium helps solving the phase problem in X-ray crystallography.
