title: Enzymic and chemical synthesis of epilson-N-(L-propionyl-2)-L-lysine.
abstract: Pyruvate was shown to act as an oxo acid substrate in the reverse direction of saccharopine dehydrogenase [epsilon N-(L-glutaryl-2)-L-lysine: NAD oxidoreductase (L-lysine-forming)] reaction. The enzymic condensation product of lysine and pyruvate was isolated and identified as epsilon-N-(L-propionyl-2)-L-lysine by comparison with the synthetic compound. A method for the chemical preparation of diastereoisomers of epsilon-N-(propionyl-2)-L-lysine is also described.
