Application
脂肪酶在工业上用于拆分手性化合物和生物柴油的酯交换生产。
从洋葱假单胞菌提取的脂肪酶已用于：
从洋葱假单胞菌提取的脂肪酶已用于：
- 催化聚已酸内酯支架的降解
- 在外消旋 Morita-Baylis-Hillman 加合物的酶解动力学过程中催化 Morita-Baylis-Hillman 乙酸酯的水解
- 作为标准品用于生成校准曲线，以测定微生物（从城市污水处理厂用于生产乙醇的污泥中分离）产生的脂肪酶的活性。
Biochem/physiol Actions
脂肪酶催化三酰甘油的羧酸酯键水解，产生甘油和游离脂肪酸。甘油三酸酯、甘油二酸酯和甘油单酸酯被水解（按降序排列）。三酰基甘油脂肪酶专门水解三酰基甘油的外部链接，并专门在水-脂质界面上运作。脂解过程中形成的脂解产物和中间产物参与了多种细胞信号传导过程。脂肪酶具有广泛的底物特异性和高度的对映体选择性。脂肪酶的此特性使其成为有机合成的良好催化剂。脂肪酶在脂肪消化和代谢中起着至关重要的作用。
General description
研究领域：细胞信号传导
脂肪酶是一种水解酶，在自然界中无处不在。它属于 α/β-水解酶折叠家族。脂肪酶的结构在活性位点含有两亲性螺旋盖结构域，有助于蛋白质的界面活化。

Magnetic cellulose nanocrystals (MCNCs) were prepared and used as an enzyme support for immobilization of Pseudomonas cepacialipase (PCL). PCL was successfully immobilized onto MCNCs (PCL@MCNC) by a precipitation-cross-linking method. The resulting PCL@MCNC with a nanoscale size had high enzyme loading
