Sucrose is a natural product occurs widely in nature. In living organisms such as plants, sucrose phosphate synthase (SPS) is the key rate-limiting enzyme for sucrose synthesis. SPS catalyzes the synthesis of sucrose-6-phosphate, which is further hydrolyzed by sucrose phosphatase to form sucrose. Researches on SPS in recent decades have been focused on the determination of enzymatic activity of SPS, the identification of the inhibitors and activators of SPS, the covalent modification of SPS, the carbohydrate distribution in plants regulated by SPS, the mechanism for promoting plant growth by SPS, the sweetness of fruit controlled by SPS, and many others. A systematic review of these aspects as well as the crystal structure and catalytic mechanism of SPS are presented.

蔗糖磷酸合酶的功能、结构及催化机制综述。

蔗糖是自然界中广泛存在的天然产物。在植物等生物体中，蔗糖磷酸合酶 (SPS) 是蔗糖合成的关键限速酶。SPS催化6-磷酸蔗糖的合成，蔗糖磷酸酶进一步水解形成蔗糖。近几十年来对SPS的研究主要集中在SPS酶活性测定、SPS抑制剂和活化剂鉴定、SPS共价修饰、SPS调控植物碳水化合物分布、SPS促进植物生长机制等方面。 SPS，由 SPS 控制的水果甜度等等。系统综述了这些方面以及 SPS 的晶体结构和催化机制。
