C_4植物光合作用中主要同功酶的测定

DETERMINATION ON THE MAIN ISOENZYME IN THE PHOTOSYNTHESIS OF C_4 PLANTS

在研究Ｃ４植物光合作用的机理上，确定光合作用主要同功酶的活性部位，利用聚丙烯酰胺凝胶圆盘电泳证明叶肉和维管束鞘细胞中存在磷酸烯酸式丙硐酸（ＰＥＰ）羧化酶和天冬氨酸转氨酶同功酶。并讨论光合作用的主要特点（１）。

To study the mechanism in photosynthesis of C4 plants, and to determine the activedposition of isoenzyme we prove that there are carboxylase of phosphoenolpyruvic acid(PEP) and transaminasc of aspartic acid in the leaf flesh and bundle sheath cell, bymeans of polypropylencamide gel disc electrophoresis.
