            Methyltransferases
SYSNAME     S-Adenosyl-L-methionine:L-homocysteine S-methyltransferase
REACTION    S-Adenosyl-L-methionine + L-Homocysteine =
            S-Adenosyl-L-homocysteine + L-Methionine
SUBSTRATE   S-Adenosyl-L-methionine

PRODUCT     S-Adenosyl-L-homocysteine
            L-Methionine
COMMENT     The bacterial enzyme uses S-methylmethionine as donor more
            actively than S-adenosylmethionine.
