    Abstract: A high-LPI lysolecithin and methods related to the same are provided. The high-LPI product is produced through the reaction of lecithin with a unique method using solvent, buffer, and phospholipase. Using the current production method, LPI content is increased from 1.4% to 2.5-13.1% using regular soy lecithin as the starting material and LPC, LPE and LPA contents are also increased from 5.1%, 2.0%, 1.0% to 15.8%, 14.6% and 4.4% respectively.

    Abstract: 一种转氨酶突变体及其应用。其中,该转氨酶突变体的氨基酸序列是由SEQ ID NO:1所示的氨基酸序列发生突变得到的氨基酸序列,突变至少包括如下突变位点组合之一:T7C+S47C、Q78C+A330C、V137C+G313C、A217C+Y252C和L295C+C328C;或者转氨酶突变体的氨基酸序列具有发生突变的氨基酸序列中的突变位点,且与发生突变的氨基酸序列具有80%以上同源性的氨基酸序列。所述转氨酶突变体实现蛋白质结构和功能的改变,减少了酶用量,提高了产物的ee值,降低了后处理的难度,使得其能够适合工业化生产。
