• 介紹：

• 活力定義：one unit causes the hydrolysis of micromole of sialyllactos(oxidation of one micromole of NADH)per minute at PH 6.5 at 37℃

• Molecular weight ：52 kDa (SDS-PAGE)

• Isoelectric point 5.86

• Michaelis constant: 1.02mM(sialyllactose pH6.5)

• Optimum pH: 5.0

• Optimum temperature: 50℃（酶活最高，不是最穩(wěn)定的溫度，穩(wěn)定溫度建議40℃以下）

• pH Stability ：4.0~10.0 (25℃, 25hr)

• Thermal stability ：< 40℃ (pH 7.5, 10min)

• Enzyme Commission Number: EC 3.2.1.18 神經(jīng)氨酸酶也稱唾液酸酶（EC 3.2.1.18）。神經(jīng)氨酸酶負(fù)責(zé)催化唾液酸與糖蛋白之間糖苷鍵的水解形成游離的N-乙酰神經(jīng)氨酸，而游離的 N-乙酰神經(jīng)氨酸在N-乙酰神經(jīng)氨酸醛縮酶的作用下裂解產(chǎn)生丙酮酸。此酶可與N-乙酰神經(jīng)氨酸醛縮酶、乳酸脫氫酶、丙酮酸氧化酶一起檢測唾液酸的含量。
