阿魏酸酯酶功能特性及应用概述

阿魏酸酯酶(ferulic acid esterase,FAE)广泛存在于自然界,属于羧酸酯水解酶的一个亚类。经过一系列反应,其能将天然半纤维素和果胶中的酚酸、阿魏酸(ferulic acid,FA)及对香豆酸等释放出来,是一种具有应用潜力的酶。因此,各行业通过相关科学技术来利用FAE,以获得如人畜食品、纸浆和纸张、燃料乙醇和药物制剂等产品。该文对阿魏酸酯酶的酶学特性、生产研究、结构解析及生物技术中的潜在应用等方面进行综述,旨在工业需求的推动下,加快阿魏酸酯酶的科学研究发现,进行知识转移,对该类物质实现高效利用,并致力于植物生物质转化和生产高附加值分子的生物合成。

The functional characteristics and application of ferulic acid esterase

Ferulic acid esterase(FAE)is an enzyme with potential application,which can be widely found in nature and belongs to a subclass of carboxylic acid ester hydrolase.After a series of reactions,it can release phenolic acid,ferulic acid(FA)and p-coumaric acid from natural hemicellulose and pectin.It is used to obtain several different products,such as human and animal food,pulp and paper,fuel ethanol and pharmaceutical preparations.This paper reviews the enzymatic characteristics,production,structure analysis and potential applications of FAE.The aim is to accelerate scientific research of ferulic esterase driven by industrial demand,promote knowledge transfer,realize efficient utilization of such material,and contribute to the transformation of plant biomass and the production of high value-added molecules biosynthesis.
