蔗糖磷酸化酶（Sucrose Phosphorylase，SP，EC2.4.1.7）主要存在于微生物和植物中，属于糖基水解酶13 家族，是一种催化转移葡萄糖苷键的酶，能够催化蔗糖和无机磷酸盐合成 1-磷酸-葡萄糖。该酶主要以蔗糖、1-磷酸葡萄糖为供体，多类物质如多羟基的糖和糖醇、酚羟基、羧基等为受体，催化合成各种糖苷。该产品可检测植物组织、真菌样本。在该试剂盒中，SP 能够催化蔗糖产生 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 340 nm 光吸收值增加。通过 340 nm 吸光度的增加速率来反映SP活性。
Sucrose Phosphorylase (SP, EC 2.4.1.7) is mainly found in microorganisms and plants. It belongs to the glycoside hydrolase family 13 and is an enzyme that catalyzes the transfer of glucosidic bonds, enabling the synthesis of glucose-1-phosphate from sucrose and inorganic phosphate. This enzyme primarily uses sucrose and glucose-1-phosphate as donors, and various substances such as polyhydroxy sugars and sugar alcohols, phenolic hydroxyl groups, and carboxyl groups as acceptors, catalyzing the synthesis of various glycosides. This product is suitable for detecting plant tissue and fungal samples. In this kit, SP catalyzes the production of glucose-1-phosphate from sucrose. Glucose-1-phosphate is then isomerized to glucose-6-phosphate catalyzed by phosphoglucomutase. Subsequently, glucose-6-phosphate dehydrogenase reduces NADP⁺ to generate NADPH, resulting in an increase in absorbance at 340 nm. SP activity is reflected by measuring the rate of increase in absorbance at 340 nm.
