Mechanisms of S-adenosylmethionineThe mechanisms below have been extracted from MACiE. The substrates and products are abstracted to their essential parts, which are necessary to explain the reaction the cofactor takes part in. The atoms involved in the next step are highlighted in red, and the ones that have been changed by the last step are shown in green. Red takes precedence when both applies.Mechanism #1 for S-adenosylmethionine
Description of mechanismIn methyl-transfer, the mechanism works via a bimolecular nucleophilic substitution. In radical reactions, a radical is formed by a one electron transfer from flavodoxin or ferredoxin [3]. This is to abstract a hydrogen atom either directly from the substrate or from a glycine residue [1]. References
