Adenosylmethionine cyclotransferase

In enzymology, an adenosylmethionine cyclotransferase (EC number|2.5.1.4) is an enzyme that catalyzes the chemical reaction

:S-adenosyl-L-methionine $ightleftharpoons$ 5'-methylthioadenosine + 2-aminobutan-4-olide

Hence, this enzyme has one substrate, S-adenosyl-L-methionine, and two products, 5'-methylthioadenosine and 2-aminobutan-4-olide.

This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is S-adenosyl-L-methionine alkyltransferase (cyclizing). This enzyme is also called adenosylmethioninase.
