S-adenosyl-L-methionine biosynthesis(SAM) is synthesized in the cytosol of the cell from L-methionine and ATP. This reaction is catalyzed by methionine adenosyltransferase. L methione is taken up from the environment through a complex reaction coupled transport and then proceeds too synthesize the s adenosylmethionine through a adenosylmethionine synthase. S-adenosylmethionine then interacts with a hydrogen ion through an adenosylmethionine decarboxylase resulting in a carbon dioxide and a S-adenosyl 3-methioninamine. This compound interacts with a putrescine through a spermidine synthase resulting in a spermidine, a hydrogen ion and a S-methyl-5'-thioadenosine. The latter compound is degraded by interacting with a water molecule through a 5' methylthioadenosine nucleosidase resulting in an adenine and a S-methylthioribose which is then release into the environment
