S-AI在pH 为4.5~5.0（酸性）条件下催化蔗糖不可逆地分解为果糖和葡萄糖，是土壤微生物蔗糖代谢关键酶之一。 测定原理：S-AI催化蔗糖降解产生还原糖，进一步与3,5－二硝基水杨酸反应，生成棕红色氨基化合物，在510nm有特征光吸收，在一定范围内510nm光吸收增加速率与AI活性成正比。
S-AI catalyzes the irreversible decomposition of sucrose into fructose and glucose under acidic conditions (pH 4.5–5.0) and is one of the key enzymes in sucrose metabolism in soil microorganisms. Determination principle: S-AI catalyzes the degradation of sucrose to produce reducing sugars, which further react with 3,5‑dinitrosalicylic acid to form a reddish‑brown amino compound with characteristic light absorption at 510 nm. Within a certain range, the rate of increase in absorbance at 510 nm is proportional to AI activity.
