In enzymology a methionine decarboxylase (EC 4.1.1.57) is an enzyme that catalyzes the chemical reactionL-methionine 3-methylthiopropanamine + CO2Hence this enzyme has one substrate L-methionine and two products 3-methylthiopropanamine and CO2.This enzyme belongs to the family of lyases specifically the carboxy-lyases which cleave carbon-carbon bonds. The systematic name of this enzyme class is L-methionine carboxy-lyase (3-methylthiopropanamine-forming).
