Abstract: | An enzyme was isolated from germinating peanut seed and shown to be an aminotransferase specific for the d-enantiomorph of methionine. The keto acid of methionine, α-keto-γ-methylthiobutyrate, was isolated from the reaction mixture and identified. Of the keto acids tested pyruvic acid was the most effective acceptor for the amino group of methionine. A small amount of enzyme was isolated which gave only one band on disc gel electrophoresis. |
