Character:
为粘多糖的分解酶,可水解组织基质中的主要成分透明质酸,增加组织的通透性,从而促使皮下输液和局部积贮的渗出液或血液的吸收。临床可用于加速皮下、肌肉注射药液的吸收,促进局麻药的浸润,减轻注射部分疼痛,促进手术及创伤后局部水肿或血肿的消散。Enzyme Commission (EC) Number: 4.2.2.1 透明质酸酶是从牛睾丸中分离提取的,并进一步用层析的方法制备,以去除残留的其它蛋白酶的污染。 Unit Definition One unit will cause a change in A600 of 0.330 per minute at pH 5.7 at 37°C in a 2.0 ml reaction mixture (45 minute assay).

用途 透明质酸酶在β-D-GalNAc-(1→4)-β-D- GlcA键处裂解透明质酸,产生3-(4-deoxy-β-D-gluc-4-enuronosyl)-N-acetyl-D-glucosamine 四糖或六糖。该酶专一作用于透明质酸,对软骨素(chondroitin)和硫酸软骨素(chondroitin sulfate)无活性。
