General description
米曲霉脂肪酶是一种羧酸酯酶，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。
Application
来自米曲霉的脂肪酶已被用于：
- 三酰甘油 (TAG) 的部分消化
- 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
- 亚麻籽油的水解
Biochem/physiol Actions
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。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。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。米曲霉脂肪酶有望用于以废食用油生产生物柴油。
Preparation Note
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

Bioconjugates established between anionic polyethylene glycol (PEG) based polymers and cationic proteins have proven to be a promising strategy to engineer thermostable biocatalysts. However, the enzyme activity of these bioconjugates is very low and the mechanism of non-covalent PEG-stabilization is

Thraustochytrium is a marine protist that can accumulate a large amount of very long chain polyunsaturated fatty acids (VLCPUFA) in triacylglycerols (TAG). How these freshly synthesized VLCPUFAs are channeled into TAG remains unknown. In this study, the glycerolipid profile of

(12-Ricinoleoylricinoleoyl)diricinoleoylglycerol (RRRR), a tetraacylglycerol, was identified earlier in castor oil. Using ESI-MS (4), 95% of the 12-ricinoleoylricinoleoyl chain was identified at the sn-2 position of the glycerol backbone of RRRR. Regiospecific location of the 12-ricinoleoylricinoleoyl chain of RRRR on the
