摘要：

The enzyme, aspartate kinase (AK) which is regulated through feedback mechanism by its end products, lysine and threonine, controls aspartate metabolism in plants. Here evidence is provided that intracellular signalling molecules such as Ca2+, protein kinases and phosphatases also participate in regulating AK activity in immature seeds of Cicer. Elevated levels of intracellular Ca2+ activate AK, which is mediated through protein phosphorylation cascade. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
