A simple and rapid method for the purification of arylsulfatase A (EC 3.1.6.1) from sheep brain has been developed. This includes the concanavalin A-Sepharose affinity chromatography and the pH-dependent polymerization and depolymerization of the enzyme. By these methods a homogeneous enzyme was obtained and the enzyme was purified 7180-fold. Sheep brain arylsulfatase A has been shown to be a glycoprotein containing 25% neutral sugar and 0.5% sialic acid. The constituent neutral sugars were identified as glucose and mannose.
已开发出一种从羊脑中纯化芳基硫酸酯酶A（EC 3.1.6.1）的简单快速方法。该方法包括伴刀豆球蛋白A-琼脂糖亲和色谱法以及该酶的pH依赖性聚合和解聚。通过这些方法获得了一种均一的酶，该酶被纯化了7180倍。已证明羊脑芳基硫酸酯酶A是一种糖蛋白，含有25%的中性糖和0.5%的唾液酸。组成性中性糖被鉴定为葡萄糖和甘露糖。
