Activating this phosphatase is accomplished by a specific transmethylase, the phosphatase methyltransferase 1, which is SAM dependent (33).

Furthermore, many transmethylation reactions are inhibited by AdoHcy through its competition with the natural substrate, S-adenosylmethionine (AdoMet), for binding domains in transmethylase enzymes (15-18).
