WebL-Methionine gamma-lyase (MGL) is a pyridoxal 5'-phosphate (PLP) dependent enzyme that catalyzes gamma-elimination of L-methionine. The crystal structure of MGL from Citrobacter freundii has been determined at 1.9 A resolution. The spatial fold of the protein is similar to those of MGLs from Pseudomonas putida and Trichomonas vaginalis. WebThe spectrophotometric assay is validated through product analysis by H-1 NMR (nuclear magnetic resonance), which showed that under the conditions of study L-methionine (L-met) and L-methionine sulfone (L-met sulfone) substrates were converted to alpha-KB product with greater than 99% yield.
