Abstract
When isolated wheat (Triticum aestivum) chloroplasts were illuminated, the activity of sedoheptulose bisphosphatase increased severalfold. The rate of activation was limited by the size of the carbon pool, and experiments with a partially purified enzyme preparation showed that the degree of reductive activation of the enzyme is governed by the concentration of its substrate.
摘要
当分离出的小麦（普通小麦）叶绿体受到光照时，景天庚酮糖二磷酸酶的活性增加了几倍。激活速率受碳库大小的限制，并且对部分纯化的酶制剂进行的实验表明，该酶的还原激活程度受其底物浓度的控制。
