植物磷酸烯醇式丙酮酸羧化酶的研究进展

The research progress of plant phosphoenolpyruvate carboxylase

磷酸烯醇式丙酮酸羧化酶(Phosphoenolpyruvate carboxylase,PEPC),是一个广泛存在于细菌、古细菌、蓝藻细胞、绿藻、原生动物和维管植物中的细胞质酶。PEPC在植物种子萌发、种子的形成、调节有机酸类的代谢、抗生物和非生物胁迫中有重要的作用。本研究主要介绍了植物PEPC种类、结构、PEPC在植物中的作用,及其在基因工程方面的研究。

Phosphoenclpyruvate carboxylase （PEPC） is a cytophasmic enzyme which is widely disterbuted in archaea, bacteria, cyanobacteria, green algae, protozoa and vascular angts. PEPC play a important role in seed formation and germicnation, regulating themetabolis of organic acids, abiotic nd biotic stresses. In this review, we mainly introduced classification, structures, fuctiongs of PEPC in plant and the progress in genetic engineering of PEPC.
