應用
黑曲霉来源果胶酶可用于:
- 原生质体释放
- 原生质体酶混合物,进行酶解
- 糖的部分糖化
- 研究其在植物病原菌入侵植物组织、农产品变质、各种食品加工和植物生物技术应用中的作用
用于植物原生质体制备,在细胞器分离前消化细胞壁。
生化/生理作用
从黑曲霉中选定菌株生成的果胶酶制剂:主要含有果胶转移酶、多聚半乳糖醛酸酶和果胶酯酶以及少量的半纤维素酶和纤维素酶。果胶酶水解果胶,果胶是细胞壁的一个组成部分。它们可能攻击甲基酯化果胶或去酯化果胶。它是果胶酶活性的来源,还含有纤维素酶和半纤维素酶活性。果胶酶催化果胶和其他半乳糖醛酸中的a-(1-4)-Dgalactosiduronic键的随机水解。
單位定義
在25°C条件下,当pH为4.0时,一个单位每分钟将释放从多聚半乳糖醛酸中得到的1.0 μ摩尔的半乳糖醛酸。
外觀

实验方案
在测定果胶酶活性时,使用了一种滴定终止反应法进行测定。在25 °C、pH 4.0条件下,一个单位的果胶酶每小时可从多聚半乳糖醛酸释放1 μmol 的半乳糖醛酸。
To measure pectinase activity, a titrimetric stop reaction assay is used. One unit of pectinase will liberate 1 μmol of galacturonic acid from poly-galacturonic acid per hour at pH 4.0 at 25 °C.
