在进化树中，C型溶菌酶和I型溶菌酶更接近一些，而G型溶菌酶位于C型和I型溶菌酶的基部。

Two inducible and extracellular chitosanases secreted by Penicillium sp. D-l were purified by ammonium sulfate precipitation as well as gel filtration. The purified enzymes of ChoA and ChoB had molecular masses of 93 and 21 kDa by SDS-PAGE. Both ChoA and ChoB have an acidic pH optimum, which were 4.0. The enzymes were stable over the pH range 3 to 5 for 1 h.

采用(NH_4)_2SO_4盐析法和凝胶过滤层析对Penicillium sp.D-1的壳聚糖酶进行分离提纯，得到两种壳聚糖酶，酶A经变性聚丙烯酰胺凝胶电泳分析，结果显示该酶的分子量约为93 kD；酶B经非变性聚丙烯酰胺凝胶电泳和SDS-PAGE分析，得出分子量约为21 kD。

The activities of PPO、POD、PAL were tested at different varieties inoculated Cladosporium cladosporioides .

本文对不同抗感品种感染污点病菌后，植株体内防御酶系过氧化物酶、多酚氧化酶、和苯丙氨酸解氨酶的变化进行了初步研究。

Fruits of mango cultivar Yuexi No.1(Mangifera indica L.) at the mature stage were collected and detected in terms of starch, glucose, fructose and sucrose, as well as acid invertase, neutral invertase, sucrose synthase and sucrose phosphate synthase.

以粤西1号为试材研究了芒果果实成熟阶段淀粉、葡萄糖、果糖和蔗糖的含量以及蔗糖代谢相关酶-酸性转化酶、中性转化酶、蔗糖合成酶和蔗糖磷酸合成酶的活性变化。

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。
