                    S-adenosyl-L-methionine biosynthesis~Biosynthesis of S-adenosyl-L-methionine (SAM, AdoMet). Conversion of L-methionine and ATP into S-adenosyl-L-methionine (AdoMet, SAM), which is required for methyltransferase reactions in the cell as well as for polyamine biosynthesis. This reaction occurs during the activated methyl cycle. |
