應用
S-(5′-腺苷)-L-甲硫氨酸（SAM，AdoMet）被用作哺乳动物细胞培养物的主要甲基供体分子以及甲硫氨酸生物合成的第一步代谢物。
生化／生理作用
甲基供体；作为酶催化甲基化的辅因子，包括儿茶酚O-甲基转移酶（COMT）和DNA甲基转移酶（DNMT）。 虽然它存在于所有细胞中，但在肝脏中较为集中，85%的甲基化反应发生在肝脏。 它还参与调节肝功能、生长和对损伤的反应中。
注意
该材料在室温下非常不稳定。

Human catechol-O-methyltransferase (COMT) catalyzes a methyl transfer from S-adenosylmethionine (AdoMet) to dopamine. Site-specific mutants at three positions (Tyr68, Trp38, and Val108) have been characterized with regard to product distribution, catalytic efficiency, and secondary kinetic isotope effects. The series of mutations

S-Adenosylmethionine, abbreviated as SAM, SAMe or AdoMet, is the principal methyl group donor in the mammalian cell and the first step metabolite of the methionine cycle, being synthesized by MAT (methionine adenosyltransferase) from methionine and ATP. About 60 years after

The sequence-specific transfer of methyl groups from donor S-adenosyl-L-methionine (AdoMet) to certain positions of DNA-adenine or -cytosine residues by DNA methyltransferases (MTases) is a major form of epigenetic modification. It is virtually ubiquitous, except for some notable exceptions. Site-specific methylation

DNA methyltransferases are important enzymes and their inhibition has many potential applications. The investigation of DNA methyltransferases as well as screening for potential inhibitors requires specialized enzyme assays. In this chapter, we describe three DNA methyltransferase assays, each of them
