Description

This enzyme selectively cleaves highly sulfated polysaccharide chains containing 1-4 linkages between N-sulfated glucaoamine and 2-O-sulfated iduronic acid. It cleaves heparin sulfate but only to a limited extent in the sulfated zone. It also cleaves the antithrombin III pentasaccharide unit in the heparin molecule.

Optimum pH 7.0-7.6. Stabilised with 0.2-0.4% BSA (Sigma A4378), 0.22 µm sterile filtered and dispensed into sterile tubes/vials.

CAS Number9025-39-2
Molecular Weight42.8 kDa
EC Number4.2.2.7
dextra的血型抗原是在红细胞表面表达的寡糖,由末端糖决定。生物合成通过A或B糖基转移酶对H抗原的作用来实现,以形成A或B聚糖。在缺乏这两种糖基转移酶的个体中,H抗原保持未修饰状态,从而导致个体为O型血。这些抗原的表达不仅限于红血球,还可以在上皮细胞和其他细胞上发生。血型由ABO基因决定,该基因编码形成A,B和H抗原的糖基转移酶。A和B血型的等位基因显示共同优势,而O型血型的等位基因是隐性的,产生了熟悉的4种ABO血型。
