S-Adenosylhomocysteine + Water → S-ribosyl-L-homocysteine + Adenine
5-Methyltetrahydrofolic acid + Homocysteine → L-Methionine + Tetrahydrofolic acid
S-ribosyl-L-homocysteine → Homocysteine + autoinducer 2
5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase
5-methyltetrahydrofolate--homocysteine methyltransferase or methionine synthase
Adenosine triphosphate + L-Methionine + Water → Phosphate + Pyrophosphate + S-Adenosylmethionine
Dimethylglycine + S-Adenosylmethionine → Hydrogen Ion + S-Adenosylhomocysteine + βine
