A) Effects of different reaction components on the activity of M‐StDAPDH. B) Relative activity of M‐StDAPDH when different concentrations of l‐threonine were added to the reaction mixture; the specific activity toward the 2‐oxobutyric acid without the addition of l‐threonine was defined as 100 %. C) Time course for the reductive amination of 2‐oxobutyric acid when 0, 100, or 200 mm l‐threonine was added into the reaction mixture.
