一般描述
脂肪酶是一种存在于动物、植物和各种微生物中多功能酶。它被视为一种稳定的天然催化剂。′南极假丝酵母脂肪酶 A（CALA）和南极假丝酵母脂肪酶 B（CALB）是由南极假丝酵母产生的两种脂肪酶。CALA 是一种耐热蛋白，在酸性 pH 下基本稳定。CALB 在碱性 pH 下稳定。CALA 和 CALB 在其固定化状态下非常稳定，可在高温下长时间 使用而不失去其活性。
生化/生理作用
脂肪酶能够在水脂界面将脂肪水解成脂肪酸和甘油，并能够在非水条件下逆转其活性。微生物脂肪酶主要应用于各种工业或商业应用。CALA 可能特别适用于重分枝底物的转化。CALA 对位阻醇，特别是叔醇有明显的活性。CALB 具有广泛的底物特异性，包括区域选择性和对映选择性。
单位定义
1U 对应于在 pH8.0 和 40℃ 下每分钟释放 1 μmol 油酸的酶量（三油精，货号 62314 作为底物）
