Identification
Name: S-Adenosylmethionine
Description:S-Adenosylmethionine is a physiologic methyl radical donor involved in enzymatic transmethylation reactions and present in all living organisms. It is made from adenosine triphosphate (ATP) and methionine by methionine adenosyltransferase (EC 2.5.1.6). Transmethylation, transsulfuration, and aminopropylation are the metabolic pathways that use S-Adenosylmethionine. In bacteria, SAM is bound by the SAM riboswitch, which regulates genes involved in methionine or cysteine biosynthesis. (Wikipedia)
