Phenylmethylsulfonyl fluoride (174.2 mg/mL), chicken ovomucoid (1000 mg/mL) and soy-bean trypsin inhibitor (1000 mg/mL) could inhibit enzyme activity, which indicated that the enzyme belonged to serine protease group. On plasminogen-free fibrin plates and plasminogen fibrin plates, the fibrinolytic activity had no obvious difference, indicating that the enzyme was a fibrinolytic enzyme which degraded fibrin directly, but not a plasminogen activator which degraded fibrin by activating plasminogen.
此菌株产生的纤溶酶在50℃以下和pH5.0~11.0范围内具有较好的稳定性,最适作用温度为42℃;最适pH值为9.0;Mg2+、Ca2+对此酶有明显的激活作用,而Cu2+能完全抑制酶的活性;174.2 mg/mL的苯甲基磺酰氟、1000 mg/mL的鸡卵类粘蛋白和1000 mg/mL大豆胰蛋白酶抑制剂能完全抑制酶活性,初步说明此酶属于丝氨酸蛋白酶类;体外溶纤作用表明,该酶溶解纤维蛋白的方式是直接溶解,而不是通过激活纤溶酶原。
-
Lysozyme is a ubiquitous enzyme in the nature. It can kill bacterium by lysing the bacterial cell wall.
溶菌酶(lysozyme, LYZ)是自然界普遍存在的一种酶,因其能溶解细菌细胞壁具有溶菌作用而得名。
-
Comparing with chicken egg-white lysozyme which is widely used in clinic, hLYZ has many advantages: it is a natural protein in human body, so it is safe and harmless when used as a drug; its bioactivity to kill bacterium is three times higher than chicken egg-white lysozyme, and its thermal stability is much higher, too; it also has many other specific important functions which are not related with its catalysis, such as anti-virus and anti-tumor and improving immunization.
人溶菌酶与目前临床上应用最多的鸡蛋清溶菌酶相比具有以下优势:人溶菌酶是人体内的蛋白,具有天然的相容性,没有毒性和副作用;人溶菌酶比鸡蛋清溶菌酶的杀菌活性高3倍,而且热稳定性也要远高于鸡蛋清溶菌酶;人溶菌酶还有多种特有的与其自身的催化作用无关的理化作用,如抗病毒和抗肿瘤。
