Properties and Regulation of Aspartate Kinase from Barley Seedlings (Hordeum vulgare L.)
No full textAspartate kinase (EC 2.7.2.4) has been purified 8-fold and characterized from germinating barley (Hordeum vulgare) seedlings. The enzyme is inhibited 50% by 0.7 mm l-lysine and almost completely at 5 mm. l-Methionine does not affect the enzyme on its own, but at low concentrations (0.1−1 mm) increases the inhibition in the presence of lysine, indicating that the two amino acids act as cooperative feedback regulators
