id: GO:0033477
name: S-methylmethionine metabolic process
namespace: biological_process
type: go
obsolete: False

Description: The chemical reactions and pathways involving S-methyl-methionine (SMM). SMM can be converted 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.
