一般描述
S-(5′-腺苷)-L-蛋氨酸氯化二盐酸盐（SAM）有助于将甲基基团转移到蛋白质，脂类和核酸上。蛋氨酸腺苷基转移酶催化从蛋氨酸和腺苷三磷酸（ATP）合成SAM。SAM能够调节各种细胞功能，比如细胞分裂，细胞死亡，翻译，遗传稳定性，氧化剂/抗氧化剂平衡和聚胺平衡。从治疗上来说，SAM可用作人体营养补充剂，用于多种疾病比如骨关节炎和肝脏损伤。SAM还能调节转硫化反应，通过和关键酶硫醚-β-合成酶（CBS）调控域结合实现。
应用
S-(5′-腺苷)-L-甲硫氨酸氯化二盐酸盐（SAM）被用作S30细胞提取物培养基补充剂。通过石英晶体微平衡（QCM），表面等离子共振（SPR）和等温滴定量热（ITC），它可以用来测量苯邻二酚-O-甲基转移酶（COMT）和支撑脂双层以及载体互作。
生化/生理作用
甲基供体；甲基酶催化辅因子，包括儿茶酚O-甲基转移酶（COMT）和DNA甲基转移酶（DNMT）。 尽管存在于所有细胞中，它主要集中在肝脏中，这里是85%甲基化反应发生的地方。 它同样参与了调节肝脏功能，生长和伤害应答。
注意
这种材料在制备是是80%-90%纯，但是非常不稳定。已经有记录每天在25℃能够损伤10%纯度。
分析说明
纯度基于UV和HPLC。

S-Adenosyl-L-homocysteine (AdoHcy) background signal in reactions with protein arginine N-methyltransferase 1 is investigated using an ultrahigh-performance liquid chromatography tandem mass spectrometry assay that measures AdoHcy. We identify three sources of AdoHcy background: enzymatic automethylation, AdoHcy contamination in commercial S-adenosyl-L-methionine (AdoMet)
