基本信息
| Enzyme Commission (EC) Number【酶学委员会(EC)编号】 | 3.2.1.18 ( BRENDA | IUBMB ) |
| General description【一般描述】 | Recombinant, Clostridium perfringens α2-3,6-Neuraminidase expressed in E. coli. Catalyzes the hydrolysis of non-reducing terminal α2,3 and α2,6 unbranched sialic acid residues from complex carbohydrates and glycoproteins. This enzyme does not exhibit activity on α2,8 or branched sialic acids. Note: 1 mU = 1 milliunit. |
| Application【应用】 | Recommended reaction buffer: 50 mM sodium phosphate buffer, pH 6.0 |
| Warning【警告】 | Toxicity: Harmful (C) |
| Unit Definition【单位定义】 | One unit is defined as the amount of enzyme that will catalyze the release of 1 µmol of methylumbelliferone from 2ʹ-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic Acid (Cat. No. 474495) per min at 37°C, pH 5.0. |
| Physical form【外形】 | In 25 mM NaCl, 20 mM Tris-HCl, pH 7.5. |
