In enzymology an adenosylmethionine cyclotransferase (EC 2.5.1.4) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine 5′-methylthioadenosine + 2-aminobutan-4-olideHence 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.
