应用

肝素黄杆菌肝素酶III已用于裂解特定GAG。已用于研究其对与抗aFGF（酸性成纤维细胞生长因子）抗体反应的蛋白质的电泳迁移率的影响。

生化/生理作用

肝素酶III可防止体内新血管的形成。它在HNY-I和HNY、6X-G2连接处特异性降解硫酸肝素。与其他肝素酶不同，肝素酶III不含氨基酸半胱氨酸。它含有13个组氨酸残基，这是其催化作用的原因。该酶对肝素或低分子量肝素没有活性。
肝素降解裂解酶，识别硫酸肝素蛋白聚糖为其主要底物。

单位定义

在25 °C、pH 7.5条件下，一个单位每小时可形成0.1 μM不饱和糖醛酸。一个国际单位（I.U.）相当于大约600个Sigma单位。包装规格基于Sigma单位。

A thick endothelial glycocalyx contributes to the barrier function of vascular endothelium in macro- and microcirculation. We hypothesised in the current study that diet-induced hyperlipidaemia perturbs the glycocalyx, resulting in decreased dimensions of this layer and increased transendothelial lipoprotein leakage
