    2.1.1.280 | DL-selenocysteine + S-adenosyl-L-methionine |
the stereochemical orientation of the alpha-amino group is not crucial. With DL-selenocysteine or DL-selenohomocysteine as substrates, the Km decreases. This leads to the overproportional increase of specific activity with DL-selenocysteine |

| 2.1.1.280 | L-selenocysteine + S-adenosyl-L-methionine |
the enzyme is suitable for specific detoxification of selenocysteine and preventing selenium from intrusion into downstream sulfur pathways. Plays a crucial role in conferring selenium tolerance |

methylation of L-cysteine can not be detected unless the concentration is raised to 10 mM. Under this condition, the reaction velocity is approximately 1% compared with methylation of L-selenocysteine. No activity with selenocysteamine and DL-homocysteine |
