Adenosylmethionine cyclotransferase
In enzymology, an adenosylmethionine cyclotransferase is an enzyme that catalyzes the chemical reaction
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 . This enzyme is also called adenosylmethioninase.
