SP(EC2.4.1.7)主要存在于微生物和植物中，裂解葡萄糖苷键，催化葡萄糖基转移到果糖、木糖、半乳糖和鼠李糖等，合成相应的葡萄糖基低聚糖。此外，SP还能催化氢醌合成熊果苷，具有极强的美白效果，在化妆品工业中具有重要应用。 测定原理：SP能够以磷酸为受体，催化蔗糖产生1-磷酸葡萄糖，在葡萄糖磷酸变位酶催化下变位为6-磷酸葡萄糖，在6-磷酸葡萄糖脱氢酶作用下还原NADP⁺生成NADPH，导致340nm光吸收值增加。测定340nm吸光度增加速率，即可计算SP活性。
Sucrose phosphorylase (SP, EC 2.4.1.7) is mainly found in microorganisms and plants. It cleaves glucosidic bonds and catalyzes the transfer of glucosyl groups to fructose, xylose, galactose, rhamnose, and other acceptors, synthesizing the corresponding glucosyl oligosaccharides. In addition, SP catalyzes the synthesis of arbutin from hydroquinone, which exhibits strong whitening effects and has important applications in the cosmetic industry. Determination Principle: SP utilizes phosphate as an acceptor to catalyze the conversion of sucrose to glucose-1-phosphate. Glucose-1-phosphate is then isomerized to glucose-6-phosphate by phosphoglucomutase, followed by the reduction of NADP⁺ to NADPH catalyzed by glucose-6-phosphate dehydrogenase, resulting in an increase in absorbance at 340 nm. SP activity is calculated by measuring the rate of increase in absorbance at 340 nm.
