应用
L-甲硫氨酸已用于氯胺测定和丙二醛测定。它也被用作蛋氨酸测定的标准。
生化/生理作用
L-甲硫氨酸用作转甲基化和转硫化的前体。甲硫氨酸腺苷酸化导致 S-腺苷-L-甲硫氨酸（SAM）的形成。SAM 用作许多物质的甲基供体。该甲基化与免疫系统功能显着相关。因此，SAM 缺乏导致严重的联合免疫缺陷。已知 L-甲硫氨酸的代谢产物谷胱甘肽可调节免疫反应，并具有抗病毒作用。

Methionyl-tRNA synthetase (MARS) catalyzes the ligation of methionine to its cognate transfer RNA and therefore plays an essential role in protein biosynthesis. We used exome sequencing, aminoacylation assays, homology modeling, and immuno-isolation of transfected MARS to identify and characterize mutations
