S-adenosyl Mthionionine yog ib hom cosubstrate nyob hauv methyl pab pawg hloov chaw, hloov pauv, thiab aminoproylation. Txawm hais tias cov tshuaj tiv thaiv anabolic tshwm sim thoob plaws lub cev, feem ntau sam-e tsim thiab noj nyob rau hauv daim siab. Ntau tshaj li 40 methyl transfers ntawm sam-e paub, rau ntau yam substrates xws li nucleic acids, cov kua nyeem, lipids thiab cov metabolites thiab qib ob. Nws yog tsim los ntawm adenosine triphosphate (ATP) thiab methionine los ntawm methionine adenosylransferase. Sam tau pom thawj zaug los ntawm Giulio Cantoni xyoo 1952.
Hauv cov kab mob, sam-e yog khi los ntawm sam Riboswitch, uas tswj hwm cov noob muaj kev koom nrog methionine lossis cysteine biosynthesis. Hauv eukaryotic hlwb, sam-e ua haujlwm raws li kev tswj hwm ntawm ntau cov txheej txheem xws li cov metylation; Kev teb tsis muaj zog; amino acid metabolism; Hloov pauv; thiab ntau dua. Hauv cov nroj tsuag, sam-e yog qhov tseem ceeb rau biosynthes ntawm ethylene, ib qho tseem ceeb cog mormones thiab signalaling molecule.
