An enzymic synthesis of aspartame (H-Asp-Phe-OMe) has been designed and realized based on the structure-activity study of thermolysin and penicillin amidase hydrolysis of its p-substituted phenylacetyl derivatives. These compounds meet the structural and energetic requirements of two enzymic binding sites The peptide sweetener has been prepared by thermolysin - catalyzed condensation of the p-substituted
基于嗜热菌素和青霉素酰胺酶水解其对位取代的苯基乙酰基衍生物的结构活性研究,设计并实现了阿斯巴甜的酶促合成(H-Asp-Phe-OMe)。这些化合物满足两个酶结合位点的结构和能量要求。肽甜味剂的制备方法是:通过热解酶-对位取代的苯基乙酰基-Asp-OH和H-Phe-OMe的缩合反应,然后通过青霉素酰胺酶的催化,对所得产物进行脱保护。阿斯巴甜的前体。
