This review focuses on the description of recently discovered esterase enzymes involved in xylan degradation (acetyl xylan, feruloyl, and p-coumaroyl esterases). The occurrence of these enzymes in various microorganisms, assays used for determination of their activity, induction and production on different substrates, interaction with other xylanolytic enzymes, mode of action, substrate specificity, and biochemical characteristics are presented. The nature of substrates on which acetyl xylan esterase, feruloyl, and p-coumaroyl esterase are active and their role in xylan hydrolysis is emphasized. The potential applications of xylan-debranching esterases are outlined and their significance to applied microbiology is discussed.
本综述着重描述了最近发现的参与木聚糖降解的酯酶（乙酰木聚糖酯酶、阿魏酸酯酶和对香豆酸酯酶）。介绍了这些酶在各种微生物中的存在情况、用于测定其活性的分析方法、在不同底物上的诱导和产生、与其他木聚糖分解酶的相互作用、作用方式、底物特异性以及生化特性。强调了乙酰木聚糖酯酶、阿魏酸酯酶和对香豆酸酯酶所作用的底物的性质及其在木聚糖水解中的作用。概述了木聚糖去分支酯酶的潜在应用，并讨论了它们对应用微生物学的意义。
