一般描述

米曲霉脂肪酶是一种羧酸酯酶[1],属于α/β-水解酶家族。它包含一个盖子结构域(lid domain)、铰链结构域(hinge domain)和一个催化三分子Ser?His?Asp/Glu。其三维结构是与酯酶非常相似的α/β水解酶折叠。[2]

应用

来自米曲霉的脂肪酶已被用于:
  • 三酰甘油 (TAG) 的部分消化[3]
  • 蓖麻油中(12-蓖麻油酰基蓖麻油酰基)二蓖麻油酰基甘油(RRRR)的消化[4]
  • 亚麻籽油的水解[5]

生化/生理作用

脂肪酶催化单酰甘油和二酰甘油的水解,其活性受二价离子作用抑制。[1]米曲霉脂肪酶是一种工业酶,可用于食品、洗涤剂和制药行业。[6]它也被用于1,3-二油酸-2-棕榈酸甘油三酯(OPO)合成的固定化研究中。[7]米曲霉脂肪酶有望用于以废食用油生产生物柴油。[6]

制备说明

通过转基因米曲霉微生物深层发酵生产的纯化米曲霉1,3-特异性脂肪酶
