Term:S-methylmethionine biosynthetic process

Accession:GO:0010250 term browser browse the term
Definition:The chemical reactions and pathways resulting in the formation of S-methyl-methionine (SMM) from methionine and S-adenosyl-methionine (Ado-Met), catalyzed by methionine S-methyltransferase (MMT). SMM can be reconverted to methionine by donating a methyl group to homocysteine, and concurrent operation of this reaction and that mediated by MMT sets up the SMM cycle.
Synonyms:exact_synonym: S-methylmethionine anabolism;   S-methylmethionine biosynthesis;   S-methylmethionine formation;   S-methylmethionine synthesis
