一般說明
α-L-艾杜糖苷酸酶 (IDUA) 定位于人染色体4p16.3。成熟的IDUA蛋白被糖基化，并包含三糖磷酸异构酶（TIM）桶状结构域、β夹心式螺旋-环-螺旋区域和免疫球蛋白样结构域。α-L-艾杜糖苷酸酶被归类为糖苷水解酶（GH）家族39。
應用
α-L-艾杜糖醛酸酶可用于新生儿 a-L-艾杜糖醛酸酶缺乏症的白细胞测定。
生化／生理作用
α-L-艾杜糖苷酸酶突变与粘多糖贮积病I型（MPS I）有关。该酶的缺陷导致皮肤素和硫酸乙酰肝素的积累。MPS I的病理生理学伴随着颅骨变形、智力低下和疝气。
在溶酶体降解过程中，α-L-艾杜糖苷酸酶（Iduronidase ）起着至关重要的作用。它水解糖胺聚糖（GAG）（包括硫酸皮肤素和硫酸乙酰肝素） 中非还原末端的α L-艾杜糖醛酸残基。
