一般描述
酯酶属于C族羧酸酯酶。它是一种糖蛋白，主要存在于肝细胞的内质网中。
应用
Sigma的酶产品已被用于研究二价金属离子对酯酶活性的影响。
兔肝酯酶已被用于：
- 通过乙酸乙烯酯、三酰甘油、对-硝基苯基酯和丝氨酸酶抑制剂检测进行牛胆盐激活脂肪酶的比较生物物理研究
- 肽类化合物的催化和动力学分析研究
- 前药化合物（BMS-292655和BMS300043）的体外稳定性测定
- 橄榄苦苷元（oleuropein aglycone，Ole-AG）的水解
来自兔肝脏的酯酶已被用于研究氨基甲酸酯类杀虫剂的毒性作用。兔肝酯酶还被用于研究辛伐他汀对脂蛋白相关磷脂酶A(2) 的表达和活性的影响。
生化/生理作用
酯酶具有广泛的底物特异性。兔肝酯酶已被用于研究氨基甲酸酯类杀虫剂的毒性作用。兔肝酯酶已被用于辛伐他汀的水解。
酯酶在水存在的情况下催化羧酸酯水解为羧酸盐和醇。兔肝羧酸酯酶催化桉油酚衍生物的对映选择性水解。

Simvastatin is known as a pro-drug, which could be hydrolyzed by esterases to its active form, simvastatin acid. Although pharmacokinetics of simvastatin and simvastatin acid have been widely studied, hydrolysis of simvastatin to simvastatin acid during blood sampling and plasma

To differentiate esterases from lipases at the structure-function level, we have compared the kinetic properties and structural features of sequence-related esterase 1 from rabbit liver (rLE) and bile-salt-activated lipase from bovine pancreas (bBAL). In contrast to rLE, bBAL hydrolyses water-insoluble

To explore the potential of step-by-step assembly in the fabrication of biological materials, we designed and synthesized two peptide-based molecules for enzyme-instructed hierarchical assembly. Upon the treatment of alkaline phosphatase, one molecule undergoes enzyme-instructed self-assembly forming uniformed nanofibers. The other

Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) contributes to atherosclerotic plaque instability and subsequent sudden coronary death. Statins are associated with decreased stroke risk and may improve stability of atherosclerotic plaques. The present study investigated the effect of simvastatin on expression of Lp-PLA(2)
